The Model
HTUC, Totally Closed-Loop Heat Transfer Unit with integrally assembled
steam-powered condensate pump is a complete manufactured system employing
the latest technological innovations in closed-loop steam systems.
The closed-loop steam system negates flash steam loss, thereby delivering
efficient heat transfer and condensate removal, with significant savings
over conventional Heat Transfer Units. At modulating loads, the Model
HTUC operates in a vacuum, utilizing steam at optimal latent heat
values, thereby decreasing the mass (lbs.) of steam consumed. The
Model HTUC unit features an ASME Shell and Tube, U-tube Heat Exchanger;
Cast Iron Y-Stainer: Pilot-operated Steam Control Valve; and Steam-Powered
Condensate Pump with motive steam and exhaust connections. Each unit
is custom engineered and designed to meet specific system requirements.
All systems are fabricated and welded per ASME Section IX Code and
Standards, and are hydrostatically tested prior to shipment.

Example
of Typical Savings
System Steam Pressure : 30 psig
Make-up Water-side Flow rate: 15.1 gpm
Water-side flow rate based on 80 oF and temperature change from 60
oF to 140 oF.
Based on continuous system operation at maximum conditions of 8400
hr./yr., approximate energy savings are 5100 Million Btu per year.
At an estimated steam cost of $5.00 / MM Btu, potential yearly savings
are $25,270.00
