Closed-Loop Heat Transfer Unit with Steam-Powered Condensate Pump (HTUC): Fluid Handling, Heat Transfer and Energy Recovery Systems by EnviroSep

Closed-Loop Heat Transfer Unit with Steam-Powered Condensate Pump (HTUC)

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

Conditions of Operation

Max. Allowable Pressure: 125 psig / 8.6 bar
Max. Allowable Temperature: 375 oF / 190.5 oC
Note: Condensate back pressure is assumed at 0 psig unless otherwise specified.
