The FLX-PLO-EPP-F plenum boxes are part of the FLX-REKU air distribution system designed for domestic mechanical ventilation systems, so-called the MVHR system, to which an air valve and FLX-HDPE / FLX-HDPE-A ducts with a diameter of Ø75 are mounted.

The heat recovery ventilation unit HRU-PremAIR has an air flow capacity of 350 m3/h at 100 PA. Designed to use aluminum heat exchangers and EPP self-supporting casing. Heat exchangers that are used depend on the model, such as counterflow aluminium heat exchanger (HRV) or counterflow enthalpy exchanger (ERV).

EPP manifold boxes are used for heat recovery ventilation (MVHR). Due to EPP's insulating properties, MVHR manifolds do not need to be insulated. Manifold boxes are intended to distribute 75mm ducting around the house. The number of connectors varies based on the specifications of the user: 4-18 spigots.

Heat recovery ventilation unit HRUPremAIR is a modern device with 350 / 450 or 500 m3/h air flow @ 100 Pa. Unit is made from cutting edge materials aluminim heat exchanger and EPP selfsupporting casing. Depending on the model, following heat exchangers are used counterflow aluminium heat exchanger (HRV) or counterflow enthalpy exchanger (ERV). Enthalpy exchangers in HRUPremAIRE series have a polymer membrane that effectively recovers heat and moisture from the extract air. Such membrane works like a membrane in waterproof trekking clothing i.e. it allows water vapour to pass through, but not liquid water and air. The enthalpy exchanger also blocks the transfer of odours, bacteria and spores. The exchanger material, is needless to say, primarily optimized for maximum heat recovery efficiency. PremAIR air handling units optionally can be equipped with the Constant Flow system, whose task is to maintain a constant air flow in the installation.

The HRUSlimAIR heat recovery unit is designed for residential buildings. The HRU has a capacity of 250 m3/h @ 100 Pa, generated by energyefficient EC fans. Thanks to a counterflow heat exchanger made of a plastic (PET), it achieves up to 90% heat recovery An ERV version with an enthalpy exchanger that recovers moisture is also available. Builtin electric preheater protects heat exchanger against freezing, wireless radio communication connects controllers and sensors, and all of it is enclosed inside a selfsupporting, insulating EPP casing. HRUSlimAIR can be installed in up to 3 positions, thanks to a special condensate drain system.

Classical systems of the screw compressor have a regulated air cooling of the lubricating oil, which means that the excess heat is discharged into the ambient by the fan. In this way, the heat is completely lost. External heat recovery unit AirWatt is designed to efficiently exploit the waste heat, generated during compression of air in rotary screw compressors. Sometimes this represents more than 70% of the energy consumed by the rotary screw compressor for the operation. This heat can then be used to heat domestic water or for heating, at almost no additional costs. This does not only help save money but is also environmentally friendly. The unit has two separate piping systems with counterflow. Energy exchange from a compressor to sanitary water occurs in a plate heat exchanger, where compressor oil and sanitary water meets. The unit is controlled by a thermostatic valve, which prevents the compressor system from getting too cold and damaging the compressor.

In processes where there is waste flue gas heat at a relatively low temperature (e.g. chimney outlets of boilers), a significant amount of savings can be achieved by producing hot water. While the feed water fed to the boiler in steam boiler applications can be preheated with the heat taken, the hot water needed by the facility can be produced in various process chimneys. In cases where there is a low hot water demand, the flue gas temperature can be lowered below the condensation limit, and the total efficiency can be increased above 100% according to the lower heating value of the fuel. According to the application conditions, economizer design can be made with materials such as carbon steel, stainless steel, titanium or PTFE (Teflon). Economiser equipment can be designed with smoke pipe or water pipe according to process conditions, and can be offered to customers with CE marking when necessary.

HRUWALLWI model ductless heat recovery unit comes equipped with a WiFi module. Its basic parameters, including max. heat recovery 82%, airflow rate 60 m3/h, and low sound power level 38 dB (A), are identical to those of the HRUWALL units. Methods for pairing devices and controlling them are different. With the addition of a WiFi module, the device can be connected to a local wireless network and controlled via a mobile app. Moreover, the app allows the pairing of devices by assigning two or more heat recovery units to a group. It is possible to have many groups so that 1 application can serve all HRV units in a building. A temperature sensor and relative humidity sensor are built into the HRUWALLWI, and the app displays their values.

HRUWALL is a singleroom decentralized heat recovery unit for concealed installation. The unit comes with a ceramic heat exchanger which boasts a maximum heat recovery ratio of 90% (the nominal heat recovery ratio is η=74.3% as per EN 1314182011). The energyefficient EC fan changes the running direction every 70 seconds to alternate between air supply and air exhaust. Low energy consumption and extremely low operating noise make this heat recovery unit a recommended solution for nonstop operation. The heat recovery unit has three speed levels to choose from, depending on the size of the area and indoor demands. HRUWALL10025 provides a sufficient air change level in areas up to 19m2. HRUWALL15060 provides a sufficient air change level in areas up to 45m2. We recommend installing the devices in pairs.

A complete centralised cooling plant, including the required peripherals, can be set up in the absolute shortest possible time at the subsequent place of installation and is immediately ready for use by means of prefabrication and installation in a container. This way, the otherwise high investments for an operating building, the costs for installation and start-up of the plant are reduced. Container cooling plants almost have no limitations in terms of their capacity and variety of possible combinations. They are supplemented by peripheral systems such as water treatment and water preparation systems or compressed air compressors. A series of different cooling systems and the combined systems composed of these units are primarily available: Chiller Heat pump systems for heat recovery Cooling tower combined with a KU system as a closed, clean cooling circuit Air heaters for direct recovery of heat hermeticool-units hermeticool hybrid-units

HRUWALLRC is a bidirectional ventilation unit, often described as decentralized or pushpull, with regenerative ceramic heat exchanger. It is intended for single room installation, usually installed in synchronised pairs.

Waste heat boilers are the equipment used in the production of process fluids such as steam, hot water or hot water by recovering this heat in processes where there is high temperature waste heat. For example, cogeneration plants, cement plants, glass factories or steel production process chimneys are potential sources for waste heat boiler application. Design and production with CE/ASME mark can be made according to EN12952 & EN12953 & ASME standards with smoke tube, water tube or combined. Depending on the operating time of the system, the payback period for installing such boilers may be limited to several years, so they are quite attractive systems to invest in. Our team has deep experience in the design, manufacture and turnkey installation of such systems.

Waste heat recovery boiler, in steam, water or thermal oil, fire-tube or water tube, designed as per exhaust gas parameters, turnkey project flexible solutions.

Waste heat boilers produced from alloy, high alloy and stainless steel according to physical properties, content, flow and process conditions of gas are designed and produced to be Water Pipe Waste Heat Boilers and Flame Smoke Pipe Waste Heat Boilers. In the gas engines and in the gas turbine, the high-temperature waste gas resulting from the combustion is evaluated by producing waste heat boilers and steam, which increases the overall system efficiency. Waste heat boilers designed and produced for heat recycling are to be heated according to flow and process; Industrial facilities Power Plants In cogeneration plants It is used in organic rankine conversion systems (ORC). These heat recovery steam generators (HRSGs), which are used to convert steam back into electricity from steam turbine back-burning gas, are also called HRSG (Heat Recovery Steam Generator) in the Combined Cycle Power Plant (CCPP).
