HESF 1000 Central Heating Unit

– PATENT PENDING –

Steam-to-fluid plate heat exchanger utilizing steam as the heat source

Features

• The system transfers heat from “on-site” steam to a circuit of heat-transfer-fluid that enables the use of any of the DryAir accessories for heat distribution.
• Automatic temperature control allows the user to set the desired supply-fluid temperature. Temperature is maintained by modulating the flow of steam through the exchanger.
• One unit will provide enough heating capacity to heat up to 50,000 square feet! (dependent on the steam source capacity)
• Using an existing steam source could prove to be the most versatile and economical approach to delivering temporary heat on a construction site / building renovation.
