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.
