  • Page 6 AIR COOLED CHILLERS STANDARD SPECIFICATIONS COMPACT DESIGN SHELL AND TUBE WATER COOLERS The DX shell & tube chillers made of low fin copper tubes expanded into a heavy steel tubular sheets. The chiller shell & baffles are constructed of steel and brass respectively. The barrel is insulated with heavy closed cellular foam insulation.
  • Page 7 AIR COOLED CHILLERS STANDARD SPECIFICATIONS CONDENSER FANS Condenser fans are constructed with aluminum or steel or PPG or PAG blades on steel hubs with direct driven motors. All fans are statically and dynamically balanced to operate at minimum noise and vibration. Fan blades are designed with appropriate pitch angle which result in maximum airflow through the condenser coil.

    AIR COOLED CHILLERS ETHYLENE GLYCOL SOLUTION CAPACITY CORRECTION (Antifreeze) When operating in areas with temperatures below 32 F (0 C), cooler protection in the form of Ethylene glycol solution (brine solution) is required to protect cooler from low ambient freeze-up. This brine solution must be added to water loop to bring down the freezing point with a difference of 15 F (8 C) below minimum operating ambient temperature.
