The compact air handling unit series R is a Rooftop-type product, designed for decentralized ventilation, heating and cooling of commercial and industrial buildings. It allows for easy installation not only on the roof of the building, but also beside it. The unit is available in two variants: with R454C refrigerant and continuous inverter-based capacity control, or with R454B refrigerant and step (on/off) control of the heat pump. The integrated heat pump can be supplied either in a reversible version for heating and cooling, or in a cooling-only version, depending on the requirements of the specific application.

Characteristics

• Rooftop-type product, available in two refrigerant variants: R454C (inverter, GWP 148) or R454B (on/off control, GWP 466), both in class A2L
• integrated heat pump in reversible design (heating and cooling) or cooling-only design
• airflow capacities ranging from 4,000 to 30,000 m³/h (from 2354 cfm to 17657 cfm)
• design selection from 14 nominal power sizes from 20 to 150 kW
• continuous capacity control with the R454C refrigerant variant
• excellent seasonal efficiency – e.g. the 50 kW size achieves SCOP 3.96 and SEER 5.38
• option to fit a bivalent electric heater
• option to fit a liquid heater/cooler
• option to fit exhaust fans and a rotary heat recovery exchanger
• thanks to the unique frameless construction, the internal surface is smooth (no internal reinforcements, sharp edges, corners, etc.) in the standard version, with no additional installation work required (e.g. sealing joints)
• thermally insulated casing in class T2/TB3 as standard
• available in a version for industrial and coastal environments with medium salinity, class C4 according to EN ISO 12944-2 (optional, at extra cost)

• designed in accordance with the ECODESIGN requirements of EU Regulation 2016/2281
• the product complies with the Machinery Directive (2006/42/EC), the Low Voltage Directive (LVD), Electromagnetic Compatibility (EMC), the Pressure Equipment Directive (PED) and the RoHS Directive
• choice of any RAL colour shade
• high variability of the control (MaR) system – various types of controllers, remote controls and communication protocols (Modbus, BACnet, Analog) according to customer requirements
• option of remote management of the unit via the CLIMAN cloud service (climan.online), including a mobile app
• emphasis on high-quality technical workmanship and an excellent price/performance ratio
• emphasis on high quality of verified and certified purchased components – fans, heat recovery exchangers, heat exchangers and others
• emphasis on easy access for service and maintenance
• in-house service centre – immediate call-outs during the warranty period, option to book commissioning services, warranty/post-warranty service
• option to extend the warranty up to 60 months

Engineering design of the Air-Handling Units

 › Decentralized Rooftop-type air handling units can be designed using the RoofMAN design software.
 › RoofMAN offers fast and clear design, including selection of the refrigerant variant (R454C/R454B), calculation of seasonal efficiency (SCOP/SEER) and an output technical data sheet in PDF.
 › The software takes into account the requirements of the EU ECODESIGN regulation and allows compliance of the designed solution to be verified already at the project stage.
 › Our specialists will be happy to help you with the technical design of the solution free of charge.
 › If you are interested, please contact our sales representatives. CONTACTS
