Description:

CASING

Casing construction bases on the spacious frame made of aluminum profile. Casing panels has the insulation made of 45 mm thick mineral wool and 50 mm. Casings of each section have the inspection panels equipped with the clamps and grips. Casing parameters according to the EN 1886 standard: heat infiltration coefficient U=1,17 W/m2K – class T3  heating bridges influence coefficient – class Tb1, mechanical strength of the casing - class 1, leak tightness - class B, working temperature in standard version from -40C to +90C

BASES AND FEET

The units use bases or feet made of galvanised sheet metal. The height of the feet and bases depends on the unit size.

ROOF

The external versions are additionally equipped with the roof protecting them against atmospheric precipitation.

FLEXIBLE CONNECTORS

Flexible connectors protect the duct system (installation) against carrying the vibrations from the unit. They also serve to minimize the misalignment of ventilation channels. Connecting frames are made of galvanized steel.

AIR INTAKE AND AIR EXHAUST COWLS

The external versions can be additionally equipped with the air intakes and/or air exhausts.

AIR DAMPERS

Depending on the configuration, the unit can be equipped with one or several air dampers. They operate as shut-off, control and protection devices. The standard blades of the air dampers are made of aluminium. The blades in the untypical solutions can be made of galvanised or stainless steel.

FILTERS

The standard units can be equipped with panel or bag filters G4-F9 class filters. The untypical solutions can use higher H10-H13 class filters.

GAS HEATER

Gas exchangers are intended for heating the air with using the gas fuels as well as liquid fuels. Air is heated thanks to flowing on the combustion chamber surface and bunch of exchanger tubes. Power regulation depends of used burner and it could be: modulated, two-leveled, ON/OFF

REFRIGERATION SYSTEM

Cooling system consists of the evaporator and the condenser as well as scroll type compressor. Evaporator and condenser are made of copper tubes with the tubes aluminum fins pack. Compressors are placed on vibro-insulators. Cooling circuit consists of: filters and cooling medium dryers, thermostatic expansion valve, low and high pressure switches, low and high pressure manometers, regulation and protecting circuits and cooling fittings. As the cooling medium the R407c,R410A is used. Cooling system can be used for supply/exhaust units with cold recovery on cross-flow exchanger.

PLATE HEAT EXCHANGER

assembly of redrawn plates made from: » aluminum, epoxy coated aluminum, exchanger by-pass, drip tray made from acid-resistant sheet, drop separator, plates spacing depends on exchanger type – from 5 to 12 mm,

ROTARY HEAT EXCHANGER

types of rotors: condensating intended mainly for heat recovery. Moisture recovery is made only in case when exhaust air is cooled below the dew-point. enthalpy regenerator has the hygroscopic coat supporting the moisture exchange, sorptive with strong hygroscopic coat enabling very effective heat and moisture recovery through the whole year, condensation epoxy coated increasing the resistance to corrosions. drive with adjusted rotational velocity with belt transmission, brushing circumferential and lateral seals, used in the units with up to 1750 mm storey height, working environment from -40°C to +80°C, The rotational speed of the heat exchanger is, controlled by the inverter, delivered with the heat exchanger, as a standard.

EXCHANGER HEAT PUMP
