Heat exchanger type KVV 04-15

DANHEAT heat exchanger type KVV 04-15 is a series of heat exchangers mounted with Water coil.

The exchangers are mounted with the following:

Airflap for air-inlet with servomotor.
Pocket filter KS 05 for supply air, cleaning gates for filter inspection.
Pocket filter KS 05 for air-outlet, cleaning gates for filter inspection.
Fan and motor for both air-inlet and air-outlet.
Air heat exchanger produces in aluminium – all with an efficiency better than 65 %.
Underneath the heat exchangers air-inlet side is mounted a tray with drain for condensation water.
The exchanger is mounted in a cabinet made of galvanised steel plate. All cover plates are galvanised and isolated with 15 mm mineral wool.
The coil is made of copper pipes with aluminated cooling ledges.
The coil is as a standard set for warm water 70/30gr C. Max operaton pressure 4 bar.
Electrical control for the exchanger is offered according to customer specifications.

Heat exchanger type KVG 04-15

DANHEAT exchanger type KVG 04-15 is a series of heat exchangers mounted with oil or gas burner for supply heat.

This combines the heat exchangers energy profit with the advantages by an air heater, no freezing risk and extremely fast energy transmission.

The heat exchanger is mounted with the following:

Airflap for air-inlet with servomotor.
Pocket filter KS 05 for supply air, cleaning gates for filter inspection.
Pocket filter KS 05 for air-outlet, cleaning gates for filter inspection.
Fan and motor for both air-inlet and air-outlet.
Air heat exchanger made of aluminium – all with an efficiency better than 65%.
Underneath the heat exchangers air-inlet side, there is mounted a tray with drain for condensation water.
Heat exchanger for oil– or gasheating, the heat exchanger is in a welded construction and made out of stainless steel.

The exchanger is mounted in a cabinet made of galvanised steel plate. All cover plates are galvanised and isolated with 15 mm mineral wool.
Type KVG 04 – 05 is mounted with on/off oil– or gas burner.
Type KVG 08 – 15 is mounted with high/low oil burner or modulating gas burner.
Electrical control for the exchanger is offered according to customer specifications.

Heat Exchanger LUFO/Recuperator

A heat exchanger where the heat is recovered from combustion products.

Suitable for: Effective cooling or heat recovery at high temperatures on the return air.

Function
Danheat recuperator: Effective heat recovery at high temperatures.

A recuperator is used where heat recovery / cooling is required at high temperatures on the exhaust air, for example. flue gases, extract air from hardened ovens, glass industry or drying processes.

The recuperator may act as air preheater (LUFO) for combustion air or the heated air may be included in any drying process.

LUFO is manufactured from 50-2000 cubic meters per hour and can be used for exhaust air temperatures up to 900 C depending on the purpose.

LUFO is very easy to clean on the exhaust air side, either mechanically or with liquid, and can therefore be used for heavily polluted air.

The efficiency is typically set for 70% and pressure loss is very small 1 - 1.5 mbar.

The recuperator is mounted in an insulated cabinet. Exterior cladding panels can be made in galvanized steel sheet or stainless steel plates as desired.
