Enhancements to dryer range

Hi-line Industries says the new Tundra dryer will help drive down energy costs by minimising pressure drop and lowering absorbed power. 

The integral Direct Expansion technology offers a constant +3°C dewpoint at all times. Furthermore, Hi-line says the new single-cell, all-aluminium heat exchanger module gives the most efficient transfer of heat at the lowest energy cost. 

Another energy-saving feature is the variable-speed fan, which ensures only the required amount of energy is consumed. By controlling the fan speed on the refrigerant circuit, Hi-line has been able to eliminate components such as fan-pressure switches, which can often become defective in this type of dryer.

Continuing the low-energy, high-reliability theme, 2018 Tundra dryers are built with Scroll refrigerant Freon compressors, which offer low power consumption and deliver a cost-effective, long-life performance. With reliability at the forefront, Tundra 2018 models offer multiple new design features to ensure constant dewpoint at all load levels and deliver continuous dry-air performance that satisfies ISO 7183 industry standards. 

Another benefit of Tundra refrigeration dryers sees the microprocessor-based multifunctional controller linked to the condensate removal valve, thus minimising any loss of compressed air as the condensate is discharged. Full programmability ensures settings can be adjusted to suit climatic conditions. The 2018 Tundra also has the option of Hi-line’s ZLD zero-loss auto drain, which is designed to eliminate accumulated contaminants from pressurised air systems. ZLD drains incorporate a level control that ensures zero air loss during the condensate discharge process.

Tundra refrigeration air dryers are proven in applications such as workshop air and machine air in general manufacturing, as well as further uses in sectors that include packaging, textile, food, beverage, medical, dairy and automotive. Dryer selection is based on factors such as maximum compressed air flow, lowest operating pressure, maximum ambient air temperature and maximum air inlet temperature. Hi-line’s applications team can help apply a corrected capacity formula to ensure the optimum dryer is selected. 

The 2018 Tundra series comprises 16 models spanning compressed air flows from 37 to 2888 m3/h and operating pressure from 4 to 16 barg. Maximum inlet air temperature is 60°C, with ambient air temperature to 50°C. High pressure (up to 50 barg) and thermal mass versions can be ordered.
