EC2+

Water-based system Liquid chiller Tailor-made

A range of energy-efficient liquid coolers using propane (R290), a natural hydrocarbon fluid with one of the lowest global warming potentials on the market.

Tailor-made machines to suit our customers’ needs (dimensions, refrigeration and acoustic performance), incorporating new-generation regulation on the water return (comfort application) or on the water flow (process application).

Performance (according to EN 14511 standard)

Flow range: 100 to 1200 kW

Cooling capacity range: from -12°C to +25°C

Description

The EC2+ liquid chiller offers great flexibility in terms of performance.

Made from an all-aluminium structure (frame and casing), it is particularly resistant to corrosion, and weighs considerably less than steel structures.

These machines come with a 20-year anti-corrosion warranty (frame – casing)

The Bitzer ® screw compressor system offers modularity of power up to 4 stages, and can also be coupled to a frequency converter, giving it even greater flexibility.

Fitted with a multi-tube evaporator for flange connection to distribution networks, the ETT design also allows total heat recovery on plate or multi-tube exchangers.

The ETT unit is designed with a standby facility in its electrical panel for connecting and controlling the power of the network pumps.

This liquid cooler is ready to operate with its new-generation control system and is also fitted as standard with remote monitoring (‘myETTvision’ supervision).
