Pressure Vessels
Low Pressure Vessels

INTRODUCTION

The benefits of continually over feeding the evaporators of a multi-circuited refrigeration system are popular world over amongst industrial users of ammonia refrigerant. Pumped liquid ammonia is the preferred method of evaporator feed because of its simplicity and high performance. By completely wetting the inner surface of evaporator coils with an excessive flow of subcooled liquid refrigerant maximum heat transfer rates are achieved, resulting in higher system efficiency and reduced operating cost.
