Is a pre-assembled compact heat exchanger package designed specifically for building heating applications. THE PRINCIPAL - FLOODED HEAT EXCHANGER FLOODED HEAT EXCHANGER GREEN APPROACH Based on a proven concept this design utilizes the sensible & latent heat of steam and eliminates the loss of energy through flash. HOW IT WORKS A conventional heat exchanger modulates the steam inlet to control the outlet water temperature. The COMPACKHEAT controls the outlet water temperature by modulating the condensate outlet and flooding the heat exchanger. In summary instead of modulating the differential temperature as a conventional design, the COMPACKHEAT SOLUTION uses the heat transfer surface by varying the condensate level according to the process demand.
key advantages simple - No steam prv - No steam srv (no steam safety relief to roof) - No pump trap - No condensate tank - No stabilizing pump - No steam inlet control valve convenient - Pre-assembled and engineered solution - Compact design requiring less footprint - System can use high, medium or low steam pressure - Two heat exchangers types available - Smaller control valve & steam trap - No high velocity steam noises - Condensate can be lifted without pump trap - Industrial design for HVAC market precise - Final temperature set point stable ±1F energy saving - No flash steam loss (200 F condensate return) - Use of latent and sensible heat of steam - Less steam consumption - Less make-up water at the boiler - Less chemical treatment and blowdown at the boiler - Reduction of greenhouse gas
