What is ADsorption Cooling ? ADsorption cooling is a technology that allows cooling to be produced from heat rather than from electricity Water used as refrigerant, no freons, no Li-Br, no ammonia means : No hazardous leaks, no corrosion, no chemical testing, no replacement. No compressor means: No alignment, no high voltage, no high pressure, no overhaul, no oil change, no surging, no vibration or noise. Stable chilled water out-put driven by a wide range (90C to 50C) of hot water. Stable operation, even with the fluctuating hot water temperatures and flow rates that are normal in waste heat recovery applications. No back-up burner required. Simple and short start up /stop time Constant operation - 24 hours /7 days a week.
