Page 3: Introduction
A. INTRODUCTION AIR/TAK Refrigerated Fluid Chillers are of the high-efficiency type, designed to effectively remove heat from process cooling fluids by means of a refrigeration process. The process fluid temperature is reduced to the temperature required by your machinery. AIR/TAK chillers are completely automatic in all respects. As with all AIR/TAK products, minimal maintenance is required. -
Page 4: Foundation
D. FOUNDATION All chillers are completely free-standing units. Any reasonably level floor that has sufficient strength will serve as a foundation. E. PIPING When piping the main fluid lines to the chiller, the use of flexible connections are recommended to avoid piping stress and vibration. -

G. CHILLED WATER CIRCUIT 1. Chilled Water-to-Refrigerant Heat Exchanger (Evaporator): This exchanger is of the brazed plate stainless steel design. The evaporator is engineered with maximum efficiency in mind. 2. Water pump: The water pump must be checked for proper direction of operation. Set GPM by amps compared to pump curve. -

3. Evaporator: Water-to-Refrigerant Heat Exchanger: The evaporator is constructed of high quality copper tubing. Cold liquid refrigerant is efficiently fed by a venturi type distributor to each circuit. The circuiting within the evaporator is designed to insure adequate refrigerant velocity to eliminate the problem of oil return to the crankcase. 4. -

9. Automatic Water Regulating Valve: This control is found only in chillers equipped with water cooled condensers. The purpose of the valve is to control the flow of water through the condenser at a rate that is factory set to maintain a constant condensing pressure. -

ambients, high inlet fluid temperatures or high fluid flow rates. 16. Start Timer: Standard on C-1200 and larger chillers. This timing device is used in conjunction with the High Temperature Control in item 16. During start-up, this device will temporarily energize the compressors electrical circuit. -
