Hi-Line Tundra Refrigeration Air Dryers

Hi-Line Tundra Refrigeration Air Dryers


Standard Reference Conditions

Inlet Compressed Air Pressure: 7 barg

Inlet Compressed Air Temperature: 35°C @ 100% RH

Ambient Air Temperature: 25°C

Minimum Pressure Dew Point (PDP): 3°C Class 4 (ISO 8573-1)

The new generation of Fridge Dryers have been designed with energy efficiency and reliability at the forefront.  Minimal energy consumption is crucial in today’s competitive environment, the new Hi-Line Tundra dryer will help drive down your energy costs by minimising pressure drop and lowering absorbed power. The Direct Expansion technology offers a constant +3°C dewpoint at all times, unlike chilled mass dryers which can be as high as +10°C during its thermal cycle. The new single cell heat exchanger gives the most efficient transfer of heat at the lowest energy cost. By using proven worldwide components within the Tundra refrigerant system reliability is ensured. It also features within that refrigerant system, liquid receivers, line dryers, thermostatic expansion valves and a series of safety features to protect the Freon compressor and its components. The Tundra range has been designed to an engineering specification rather than a budget. Larger dryers up to 9988 cfm are available on short lead-time, although our standard range as featured here are available ex-stock for next day delivery.

Energy Saving Controller

Within the multifunctional dryer controller the display indicates the dryer running dewpoint. Should the dryer go on to light duty (i.e. reduced airflow) the refrigerant gas pressure is monitored and adjusted accordingly. The dryer has a built in energy saving device which will stop the compressor and await the refrigerant gas pressure to rise to a pre-set value before starting again. This feature thus reduces energy and also maintains a consistent dryer dewpoint of +3°C pdp at all times.
