SM RO

Groupe sur l'eau

The SM RO is a propane (R290) industrial heat pump and liquid chiller.

It is an eco-responsible, tailor-made solution for your industrial applications.

ETT offers a full range of propane (R290) liquid chillers and heat pumps, using a natural refrigerant with an almost negligible GWP of 0.02.

Designed for industrial sectors and ideally suited to decarbonisation challenges and regulatory requirements, this equipment combines energy performance, modularity and durability.

These units are fully customisable to meet technical constraints (dimensions, acoustic requirements, water temperature regimes) and your specific process requirements.

Performance (in accordance with EN 14511)

  • Capacity range: 250 kW to 1,000 kW
  • Leaving water temperature: –25°C to +70°C
  • Outdoor temperature: up to +42°C

Description

The SM RO chiller combines robustness, efficiency and innovation.

  • AG3 aluminium frame and casing for optimal corrosion resistance and reduced weight compared with steel. 20-year anti-corrosion guarantee
  • BITZER reciprocating compressors, with optional variable-speed drive for precise capacity modulation
  • High-performance heat exchangers: Evaporator/condenser: brazed plate heat exchangers (BPHE) or shell-and-tube exchangers for simplified process connection
  • Total heat recovery via a dedicated condenser, as an option
  • Ø910 propeller fans with variable speed and EC motors for optimum efficiency and low sound levels
  • Next-generation PLC:
    * Communication between units with secure data transfer to a protected cloud platform.
    * myETTvision for real-time monitoring and supervision.
    * Compatibility with standard industrial communication protocols.
