Brush-type radiator

Hydrocell brush-type radiators are a flexible and economic way of adding a heat recovery system to existing buildings and new construction.

HC-LTO radiators are also well suited to situations where exit air contains impurities such as dust or grease. Typical applications are locations in kitchens and industrial buildings.

Heat recovery systems are a cost-effective investment

  • Payback times at today’s energy prices are 3-5 years
  • Energy prices continue to rise
  • Typical lifecycles are some 20 years

Hydrocell brush-type heat transfer elements can be easily modified, so that installation can be executed as rapidly as possible and any associated costs are minimised.

  • Simplest possible solution
    • Minimises the number of heat exchangers
    • Simple methods of connection
  • Customised heat exchangers – reduce installation costs
    • Modular construction enables installation in constricted spaces without major revisions of building technology.

Using Hydrocell solutions, cost-effective heat recovery systems can be installed in all buildings that have air conditioning systems. Heat exchangers can be placed in locations where their use makes good sense:

  • Ducts
    • Heat exchangers can be installed directly into ducts
  • Balancing chamber
    • The input-air balancing chamber usually has room for a heat exchange element
  • Equipment installed on a roof
    • Boxes can be constructed to handle either incoming or outgoing air

Heat recovery systems

An incoming-air opening heater can even be fitted with a radiator in situations where there is insufficient space after the filter.

  • Heat-recovery elements can be installed in locations where solutions of this type would otherwise be too costly
  • If space for a heat-recovery element has not been provided, installation downstream of the air filter is a very expensive solution. HC heat-recovery radiators can be installed ahead of the air filter.

Installing an input-air heating element upstream of an air filter in conjunction with an air inlet:

  • Brush-type heat excahnge elements are not sensitive to dirt and impurities
    • Dirt that collects on the heat exchange elements does not significantly increase the pressure drop across the unit or reduce its efficiency
    • Brush-type heat exchangers can be cleaned using a vacuum cleaner or a high-pressure water jet
    • Space can be left between the rows of brush-type heat-exchange elements, making cleaning easier
  • An incoming-air heater helps to keep filter elements dry
    • Extends intervals between filter changes
    • As filters remain dry, microbial growth is inhibited
    • Significantly reduces the quantity of fungal spores that a filter adds to the incoming air
