HCF100 – Refrigerant Gas Sensor

Duomo (UK) Ltd

The HCF100 is a Refrigerant Gas sensor for connection to Duomo gas detector controllers. Using semiconductor technology to detect the presence of a large range of Freons including R134a, R404A, R407C, R410A as well as NH3 Ammonia. A popular feature of the HCF100 is its ability to auto calibrate under varying conditions which minimises false alarms.



Armaflex is a flexible, closed cell, elastomeric, nitrile rubber insulation. It is a highly efficient method of insulating hot and cold water services, chilled water lines, heating systems, air conditioning ductwork and refrigerated pipework for frost protection, energy conservation and condensation control. Armaflex is dust free, fibre free and CFC free with an ODP of zero which means an environmentally friendly product.


  • Lightweight and flexible means easy and speedy installation with low maintenance, resulting in time and cost savings.
  • Wide range of tube and sheet sizes available.
  • The low thermal conductivity, 0.035 W/mK at 0°C, and good acoustic performance provide double benefits with one insulation system.
  • Closed cell structure provides a built-in vapour barrier.
  • A high, 5000 μ, resistance to water vapour transmission and water ingress, gives long term insulation efficiency for condensation control.
  • Low Toxicity Index for added safety assurance.
  • Class 0 fire category means low fire propagation index, producing minimal contribution to overall heat release, and a zero surface spread of flame for a high degree of fire protection and safety.
  • Excellent resistance to the effects of ozone, oil, chemicals, extreme weather conditions and wear and tear.
  • Dust, fibre and CFC free with an ozone depletion potential of zero.
  • BS EN ISO 9002 and 14001 approval confirms continuity of quality.


  • Process work.
  • Hot and cold water services.
  • Chilled water lines.
  • Heating systems.
  • Air conditioning ductwork.
  • Refrigeration pipework and ancillary equipment.
