Frascold upgrades ATEX HT compressors
7th May 2025
ITALY: Frascold has upgraded and extended its range of ATEX HT series semi-hermetic piston compressors for hydrocarbon refrigerants.
Currently designed for use with propane, the new models can also be used with butane and isobutane and offer higher operating temperatures: up to 135°C with butane, 115°C with isobutane, and 85°C with propane.
The new compressors also offer greater modulation, operating down to 25% of maximum capacity.
The ATEX-HT compressor series comes in four sizes – S, V, Z and W – each with specific volumetric displacement values and motor power.
The most compact S model has four pistons, with volumetric displacement values ranging from 33m³/h to 56m³/h in sizes from 5-15kW. The V models are available in four models up to 93m³/h and 24kW. The six-piston Z models offer up to 126 m³/h and 30 kW. Finally, the W models feature eight pistons, with maximum values of 206m³/h and 52kW.
Permanent magnets motors are available as an option, providing a 6% increase in efficiency. Reinforced valve plates allow for pressure lifts over 30bar, while reinforced pistons with anti-friction coatings reduce wear and ensure a smoother start-up.
