DryAir at Work

“The DryAir system is without a doubt one of the most effective temporary heating systems we have used in over 50 years of doing business.”

“The modular design of the system has allowed us to use it in projects ranging from hospitals and hotels to open space warehouses.”

“We find that our setup and maintenance costs for temporary heating have been greatly reduced. To date, we have been very impressed with the system’s performance and versatility!”

“We are currently utilizing the DryAir boiler system on the New Emergency Centre at the University of Alberta Hospital.”

“This specialized heating system has a boiler housing that can be positioned anywhere on site, runs on natural gas, propane or oil, and will deliver heat up to 500 ft in multiple directions, via hot water/glycol lines, to portable fan coil assemblies.”

“Temperature control and fuel usage is automatic…. this unit requires very little supervision, therefore, cutting maintenance costs down! This helps offset the slightly higher cost of renting the DryAir unit.”
“The most practical uses for this heat are for buildings that are largely enclosed. The system provided consistent, safe dry air. This reduces drying time for drywall, paint & stucco, and curing time for concrete.”

“If this unit is included early in the planning stages on site, the lines can be run so they are hidden and tied into the duct system… this provides an “invisible” heat system for the job site and no relocating of units to accommodate other work.”

“We required a temporary heating system for this project throughout the winter of 1998/99. The building size 110,000 sq ft., consisting of over 140 different rooms.”

“This type of building would require using many burners and fans to try and supply heat and air flow in all of the various rooms. From my experience this was going to be extremely difficult, and a real problem particularly for the Drywalling people. Burners generate a lot of water, combining this with the water from the drywall mud and paint, made for a very humid environment that was detrimental to the curing process. Also the fire hazard, and toxic fumes that are associated with burners was also an issue.”

“When I saw the DryAir’s literature on their portable heating system, I felt it had potential. From what I could see, it utilized a central heating unit that was located outside the facility. The heating unit consisted of a hot water heater and controls (It looked user friendly, and fire free). The heat was transferred to heating units inside the building. These heating units could be situated at various locations within the building.”

“Looking at the system, I felt that we could hook it up to the ductwork inside the building and have the air transferred throughout the building. This would eliminate all the fans that we normally have for moving air when utilizing burners… and it would ensure warm air was circulating in all of the rooms throughout the building.”

“I thought if this system could reduce the amount of water in the building, provide a non-toxic environment for my people and be fire free! It was a system worth giving some consideration.”

“Looking back on the project, utilizing the DryAir system for our heating was a very good decision. It provided everything it was asked to do… and more!”

“Some of the advantages we experienced were:

We did not have to ventilate the building with outside air. This lead to greater energy efficiency.
Normally, when using burners, generation of toxic fumes and the depletion of oxygen levels force us to bring in vast amounts of outside air to keep air quality adequate.
No fire hazard! This eliminated the stress of waiting for a fire to happen. We did not even have to check the system at night or on weekends.
Cleaner air quality! There were no complaints of fumes. The sub trades were very happy with air quality. Many of them did not even know where the heat was coming from. I´m sure this translated into higher productivity.
Lower humidity! This was the most important issue. There were no delays in drywalling and painting. There was no ice buildup on windows or doors and no drywall staining. This was a big accomplishment for a building of this design.
We also utilized the system to heat hoarding for brick layers. This worked just fine.
Very minimal maintenance and supervision!
Worked very well for curing concrete! There was no dusting effect. This can be a real problem with burners if you are not careful.
We were also able to filter the air before it was blown into the ductwork, thus eliminating a lot of the drywall dust and paint dust from lining the duct work. This could not be done with burners.”

“By law there are only two places that direct flame burners can be utilized, one is on construction sites and the other is in pig barns. In my opinion, from what I´ve seen with the DryAir system, this type of heating should be the future and direct flame burners should be limited to only pig barns.”

“Overall, we were very impressed with the system. It provided exactly what we needed for our project, a no hassle, fire free, non-toxic environment with consistent low relative humidity air.”

“As a result, at the end of the project, we purchased the two systems we utilized from DryAir.”

“We will be utilizing DryAir for many years to come.”

“Through the winter of 1998/99, I had the experience to utilize the DryAir heating system at a 110,000 sq. ft nursing home in Saskatoon, Sask.”

“We felt this particular project was going to be difficult to drywall, not only because of the size being 110, 000 sq. ft, but because the structure contained 150 different rooms… some very small. We felt that getting the air circulation required to help the curing process was going to be very difficult.”

“The DryAir system was installed and connected to the existing duct work. This allowed for even distribution of the warm, low relative humidity air. As a result, this project turned out to be the best we worked on all winter!”

“The air quality provided by the DryAir 2000 system was ideal for the curing of drywall.

The consistent, low relative humidity air eliminated the normal high humidity problems you encounter on most winter construction sites.

Our curing time was reduced by at least 50%. There were no humidity problems, no drywall staining, no ice, therefore no delays; it was an excellent heating system.”
The improved air quality with the DryAir system also provides an excellent working environment… far better than any other temporary heating system we have worked with in the past.”

“The most common alternate method of heating has been direct flame burners. These burners generate large amounts of toxic fumes and water which, in turn creates a very poor working environment. Complaints of nausea and headaches are not uncommon.”

“Because The DryAir system’s central heat source is located outside the exterior of the building, no toxic fumes are introduced into the work area. As a result, the environment is improved. An improved environment, I believe, increases worker productivity.”

“I recommended the utilization of DryAir 2000 portable heating system whenever temporary heating is required.”

“This winter, we heated a a large 420,000 square foot truss plant project for Weyerhauser Canada . The structure had 50 to 60′ ceilings.”

“Comstock Construction was the general on the job and set up to use eleven DryAir 2000-1200 central heating units.”

“The overall performance of the DryAir system was excellent! The biggest impact on my job site was the lack of combustion by-products normally introduced by traditional burners.”

“Compared to other heating systems the DryAir system offers indirect heating which produces much better air quality. Air quality is a major concern on these types of projects.”

“The systems were also very flexible and low maintenance when compared with other types of heaters.”

“DryAir 2000 Inc. was contracted by our firm to provide temporary heating on two of our projects in the Ottawa area.”

“Under normal circumstances, both these projects would have been heated using direct flame heaters… however, after speaking to the DryAir representative, we were sold on its possible advantages.”

“On the kitchen facility project, which would have propane as a fuel, the DryAir system was sold to us on the basis of cost effectiveness; DryAir replaced 1.5 M BTU´s of direct fire units with a 600,000 BTUH boiler resulting in savings that more than offset the additional rental charges.”

“On our Canadian forces project, the DryAir system´s advantages were the most striking!

As this system was used to heat the building during the finishing stages of the project, we were able to see many of its advantages. ”

“Drywall work was the most influences with the system… the reduced curing time significantly improved on our schedule!

“By providing a more even temperature and greatly reduced humidity level, the working conditions and progress of the work were greatly enhanced!”

On our book store project, DryAir was brought in to replace direct flame units. This project had fallen considerably behind schedule and was plagued with serious ground thaw problems. Because we were able to direct heat where it was needed, DryAir was able to assist us to get our job back on track.”

“Overall, I was extremely pleased with the performance of the DryAir system and look forward to working with it again this winter!”

“We took delivery of your DryAir heating system on our Harvard Business School dormitory project in Allston, MA.”

“On this project, we were unable to utilize natural gas… and because of local regulations, could only have a limited amount of propane on site.”

“By using the DryAir system we were able to completely fulfill our heating needs in a wide variety of applications.”

“During the two and half months that we had the system on the job some service was needed and in all cases, both United Rentals and DryAir were prompt and knowledgeable.”

“After a very short learning curve our onsite staff was able to start, maintain, and troubleshoot the system with ease.”

“We found our fuels costs to be consistent with the estimates you provided at the beginning of the project.”

“In conclusion, we were extremely pleased with all aspects of the DryAir system.”

“As discussed, we look forward to using two of the DryAir units in the upcoming heating season.”

“I would like to take this opportunity to thank you for your expert assistance this past winter by recommending and providing the DryAir system.”

“This heating solution was perfectly adapted for the Administration Building Section of the new Sithe Energies Fore River 800 Megawatt Project.”

“The ease of installation and system flexibility provided us with the confidence to schedule and complete critical architectural finish activities.”

“These successful schedule completions were possible only with the aid of an effective and reliable temporary heating system and United Rentals with DryAir certainly fit the need.”

“As a Construction Superintendent in North Dakota, temporary heat has always been a major headache!”

“Currently, I am working on a two story 55,000 sq. ft building. This building has no exterior insulation on the masonary walls… just roof insulation.”

“In this situation, my biggest concern was frost and ice build-up on the exterior walls. The DryAir system took care of that. Even on the coldest days, frost was very minimal… and with the addition of a few fans our problem was totally solved.”

“The Main Benefits I see with the DryAir system are:

Safety… no open flames and no fumes, therefore, productivity is up.
Low maintenance.
Low humidity… therefore, interior finishes are easier to complete.
Even heat is very easily accomplished by moving units around.
Easy weekend checks by just looking at the control panel lights for problems.”

“In the future, if temporary heat is required, I hope it’s DryAir on the job.”

“The DryAir temporary heating equipment did a very good job for us on the Ohio Air National Guard project.”

“We heated about 8,000 square feet of office space with one base unit and eight – 80,000 BTU heat exchangers.”

“The equipment provided even heating.”

“It was easily controlled with thermostats and it didn’t introduce any additional moisture into the building.”

“We were very happy with the performance of the equipment!”

“When determining what our heating requirements were going to be, we thought that the DryAir system would be a perfect fit.”

“The addition to the school was constructed during the regular school season so we couldn’t have any open flames or excess noxious fumes present.”

“The project entailed a large amount of painting, drywall and finish work and were informed by the R& J Construction Supply representative that the DryAir system would not add any additional moisture.”

“The two DryAir systems we set up on our project provided an excellent, dry, even heat throughout the building… on all floors.”

“I was getting comments from the sub-contractors on how great the system was… especially pleased were the drywallers!”

“The flexibility of the system, along with the progressive fuel savings makes it an easy temporary heating choice.”

“We will definitely consider using the DryAir portable heating system on future projects!”
