COMPACT HEATERS

Air heaters are devices manufactured by KALFRISA for different industrial processes of drying and heating. Depending on each process and operating conditions, we are able to offer a customised, reliable and efficient solution which suits the final needs of our client.

Our equipment is classified based on the thermal gap / power exchange that will be carried out. Heating power is therefore distinguished from highest to lowest between Modular Heaters, Preheaters, VKs, VTs, LTs and Hot Air Generators.

Sectors
  • Flash drying for Food: VK Heater.
  • Dryers for solid foods such as tobacco, salt, pistachios, fruit, etc. (LT, VT)
  • Drying of Minerals: VK Heater
  • Drying of Ceramic: VK Heater
  • Automotive (VT)
  • Treatment of metallic or plastic surfaces (VT/VK)
  • Textiles (VT)

Heaters for Industrial and drying processes: VT

Indirect air heater for industrial processes. Designed to be integrated in different input units. The air heaters are used to indirectly heat air, generally recirculated, in paint curing and drying processes. They are ideal models for replacing heating devices in input units.

For drying processes in which the temperature does not exceed 300ºC and the thermal gap necessary is under 70ºC, the VT series of heaters is available. The VT heaters are easily integrated in their input unit. They are made up of an isolated front panel, combustion chamber, heat exchanger and smoke outlet. Optionally, they may be supplied with a smoke box.

Fields of application
  • Textiles
  • Minerals
  • Ceramics
  • Automotives
  • Treatment of metallic and plastic surfaces

Criteria for use

  • Useful heating power of 30,000 up to 1,200,000 Kcal/h.
  • Air temperature increase up to 40ºC (70ºC with directional plates).
  • Air outlet temperature up to 200 and 300ºC, operating with return or external air.

Heaters for Industrial and drying processes: VK

This model is the most powerful indirect air heater for industrial processes within our range . It is the heater capable of offering the greatest thermal gap, up to 450ºC. They are manufactured as a single piece to facilitate their installation at the plant, transport and handling. The air heaters are used to indirectly heat air for different processes such as flash drying for food, drying of minerals and other materials, and obtaining hot air for different uses.

They can be manufactured fully from stainless steel to guarantee fulfilment of food sector requirements. They are robust devices which tolerate thermal dilations due to use of compensators well and can operate with different types of fuels. They can be supplied in different positions and the position of their inlets and outlets can be conveniently adapted accordingly based on the needs of the client.
