MAM 250

Multi-energy absorption chiller

Description

MAM 250 absorption chillers convert heat into cooling using innovative and high-performance technology. They produce cooling down to –30 °C and simultaneously heat up to +65 °C, enabling the use of all forms of heat (renewable, industrial waste heat, etc.).

Designed and manufactured in France, these machines incorporate numerous technological innovations, allowing them to be powered by intermittent energy sources such as solar energy, particularly through Heliolight 4800 concentrated solar collector fields also developed by Helioclim.

Helioclim Multi-Energy Absorption Machines (MAM) have the following specifications:

  • Height: 4.05 m
  • Footprint: 2.2 m × 2.2 m
  • Weight: 3.5 tons
  • Lifespan: > 30 years
  • Noise level: < 10 dB
  • Power consumption: 6 kW
  • Minimum chilled water temperature: –30 °C
  • Warm water temperature: 30 to 65 °C
  • Hot water temperature: 65 to 200 °C
Operating principle

MAM systems are thermodynamic machines using ammonia as the refrigerant. The machine’s circuit is fully sealed. The fluid remains confined within the machine, does not degrade, and does not need to be replenished throughout the system’s lifetime.

Helioclim Multi-Energy Absorption Machines (MAM) offer the following advantages:

  • Reduce electricity consumption by 95% compared to a compression system
  • Simultaneously produce chilled water down to –30 °C and hot water up to 65 °C for heating or domestic hot water
  • Self-adaptive operation: the system automatically adjusts to variations in input power (e.g., solar source) and fluctuations in the building’s thermal load
  • Reliable, durable machine with minimal maintenance. Additionally, the machine is connected to a remote monitoring system to track operational parameters
  • Fully manufactured in France at our production facility in Cannes
  • All-stainless-steel construction allows installation even in harsh environmental conditions, such as tropical regions
  • The Helioclim multi-energy absorption machine can operate with primary hot water temperatures below 100 °C under certain conditions, to be studied on a project-by-project basis
