Electric Duct Heaters with Built-in Controls

IMOFA has a wide range of circular duct heaters and rectangular duct heaters with ‘built-in’ controls. Duct heaters with temperature control provide many benefits over standard heaters with separate controls. In particular, installation costs are significantly lower, and they can be easily and quickly installed with minimal cabling, and minimal risk of incorrect installation.

We are able to offer single phase duct heaters and three phase duct heaters. All our models have built in regulators with options for room thermostat, room sensor or duct sensor control. Our MQXL and MTXL models operate from an external 0 to 10 Volt Control signal. Other options are available.

As standard our heaters are made of Aluzinc-coated sheet steel but we do also offer acid-resistant stainless steel and stainless steel duct heaters. Our high temperature duct heaters are designed for outlet temperatures of greater than 50*C and we also offer weatherproof duct heaters with anti-condensation insulation and/ or produced to degree of protection IP55 or IP65 instead of the standard IP43 version if required. Please download our brochure for more details.

Circular (CV) Heaters

Uses for the CV circular electric duct heaters include tempering fresh air in ventilation systems, heating air supply to individual rooms and zones with independently controlled temperatures, and boosting supply air temperature after heat recovery units – including MVHR units in Passivhaus systems.

  • Electric Duct Heaters for 0.3 to 12.0kW
  • 100mm to 400mm duct diameter
  • Built-in electronic temperature regulator controlling heating by time-proportional regulation (pulse/pause) technology.
  • External or built-in air flow monitor
  • Alu-zinc coated sheet metal casing
  • Stainless steel heating elements
  • Can be installed horizontally or vertically
  • Protection class IP43 as standard, IP55 to order
  • Built-in dual overheat protection, automatic and manual reset
  • Complies with European Standards EN50081-1 and requirements of the low voltage directive

Rectangular (VF/VFLPG/VTL) Heaters

Installed in duct systems or within air handling units these rectangular electric duct heaters are used for efficient heating of supply air in ventilation systems and industrial processes. Flexible manufacturing enables production of configurations to match individual applications.

  • Electric Duct Heaters with ratings up to 2000kW
  • Built-in electronic temperature regulator controlling heating by time -proportional regulation (pulse/pause)
    technology.
  • For high powers step control is used for proportion of power with ‘time–proportional’ regulation providing final
    regulation and accurate control of temperature.
  • External or built-in air flow monitor
  • Alu-zinc coated sheet metal casing
  • Stainless steel heating elements
  • Can be installed horizontally or vertically
  • Protection class IP43 as standard, IP55 to order
  • Built-in dual overheat protection, automatic and manual reset
  • Complies with European Standards EN50081-1 and requirements of the low voltage directive
