The APMR-V Series Inverter Packaged Air Conditioner represents the pinnacle of packaged AC technology combining the proven reliability of hermetic scroll compressor construction with advanced inverter drive technology and electronic expansion valve (EEV) control to deliver industry-leading energy efficiency at both full-load and part-load operating conditions.
Available in capacities from 6TR to 35TR (21kW to 123kW), the APMR-V Series is engineered for demanding commercial and light industrial environments where energy cost, operational reliability, and precise temperature control are equally critical requirements. From mid-sized offices and retail establishments to hotels, schools, warehouses, and institutional buildings the APMR-V Series delivers a level of efficiency and comfort precision previously associated only with large central plant systems.
At the heart of the APMR-V Series is a high-efficiency totally sealed inverter-driven scroll hermetic compressor combining the mechanical simplicity and reliability of scroll compression with the energy-saving benefits of variable speed inverter operation. This is further enhanced by electronic expansion valves that continuously regulate refrigerant flow with precision, maintaining exact temperature control regardless of load variation or ambient fluctuation.Rated for operation between 10°C and 52°C (50°F to 125.6°F) ambient, the APMR-V Series is purpose-built for the extreme climatic demands of the Gulf region, South Asia, and Africa delivering full rated inverter performance where standard packaged units cannot operate reliably.

Inverter-Driven Scroll Hermetic Compressor
The APMR-V Series is powered by a high-efficiency totally sealed inverter-driven scroll hermetic compressor combining two of the most significant advancements in commercial packaged AC technology:
- Variable speed inverter drive – Compressor speed modulates continuously from minimum to maximum output, precisely matching real-time cooling demand without on/off cycling
- Hermetically sealed scroll mechanism – Welded steel shell eliminates shaft seals, minimises refrigerant leak risk, and provides the smooth, continuous compression geometry of scroll technology
- Optimum full-load performance – At peak demand, the inverter compressor operates at maximum efficiency delivering full rated capacity with industry-leading EER
- Superior part-load efficiency – At reduced loads, the most common real-world operating state for commercial packaged units the inverter modulates down, delivering IEER values significantly higher than fixed-speed alternatives
- Energy savings up to 40% – Inverter operation versus fixed-speed equivalents delivers substantial electricity cost reductions over the unit’s operational lifetime
- Soft-start capability – Inverter drive eliminates the high inrush current of direct-on-line compressor starting reducing electrical infrastructure stress and peak demand charges
- Extended compressor life – Smooth speed modulation eliminates the mechanical shock of on/off cycling the primary cause of compressor wear in fixed-speed systems
Electronic Expansion Valves Precise Temperature Control
The APMR-V Series incorporates Electronic Expansion Valves (EEV) a key technology that elevates system precision and efficiency beyond what is achievable with conventional thermostatic expansion valves:
- Continuous refrigerant flow regulation – EEV modulates refrigerant flow into the evaporator in real time, responding to changes in load, ambient temperature, and compressor speed simultaneously
- Optimised superheat control – Maintains evaporator superheat within tight tolerances across all operating conditions, maximising heat transfer efficiency and protecting the compressor from liquid refrigerant ingestion
- Precise temperature control – Supply air temperature is maintained within very tight tolerances regardless of load variation delivering consistent, draught-free comfort in occupied commercial spaces
- Seamless inverter integration – EEV and inverter compressor operate as an integrated system the expansion valve continuously adjusts to match the refrigerant flow requirements of the modulating compressor
- Improved part-load efficiency – Precise refrigerant metering at part-load eliminates the efficiency losses associated with conventional TXV hunting and overshooting
- Fast response – Electronic actuation responds to load changes far faster than thermostatic alternatives preventing temperature excursions during rapid load variations
Full-Load & Part-Load Performance Optimisation
The APMR-V Series is specifically engineered to deliver optimum performance at both full-load and part-load addressing the complete real-world operating profile of commercial packaged equipment:
- Full-load optimisation – At design conditions, the inverter compressor, EEV, and coil sizing combine to deliver maximum cooling capacity with industry-leading full-load EER
- Part-load optimisation – At reduced loads, which represent 60–80% of annual operating hours in commercial buildings the inverter modulates to the minimum speed required, dramatically reducing energy consumption
- IEER advantage – Integrated Energy Efficiency Ratio (IEER) the weighted part-load efficiency metric is significantly higher for the APMR-V inverter series than fixed-speed APMR-G1 equivalents
- Continuous modulation – Unlike two-stage or multi-stage fixed-speed systems, true inverter modulation provides infinite capacity steps between minimum and maximum eliminating the efficiency gaps of staged control
- No temperature hunting – Continuous capacity modulation maintains set point without the temperature oscillations caused by staged on/off compressor control
- Real-world energy savings – The combination of inverter compressor and EEV delivers measurable energy bill reductions across all seasons and occupancy patterns
Wide Ambient Operating Range 10°C to 52°C
The APMR-V Series inverter packaged unit is rated for reliable operation between 10°C and 52°C (50°F to 125.6°F) ambient:
- 52°C upper limit – Full inverter-modulated cooling capacity maintained at the extreme ambient temperatures encountered on rooftops and outdoor plant areas across the UAE, Saudi Arabia, Kuwait, and GCC during peak summer
- 10°C lower limit – Reliable inverter operation during cooler seasons without low-pressure compressor tripping or control system faults
- Inverter performance across the range – Unlike some inverter systems that limit modulation range at high ambients, the APMR-V maintains full inverter capability across the complete operating envelope
- Consistent supply air conditions – Advanced inverter controls and EEV maintain stable supply air temperature regardless of ambient fluctuation important for consistent occupant comfort across seasons
- Suitable for diverse climates – Covers UAE and GCC peak summer, South Asian tropical conditions, and African arid and humid climates in a single specification
R-410A Chlorine-Free, Eco-Friendly, Cost-Effective
The APMR-V Series operates on R-410A a refrigerant chosen for its environmental, performance, and economic advantages:
- Chlorine-free formulation – R-410A contains no chlorine atoms, eliminating any contribution to ozone layer depletion
- Zero ODP (Ozone Depletion Potential) – Fully compliant with international refrigerant regulations and UAE Ministry of Climate Change and Environment requirements
- Cost-effective – R-410A is widely available across global supply chains ensuring competitive service and maintenance costs throughout the unit’s operational life
- High operating efficiency – R-410A operates at higher pressures than older refrigerants, enabling more efficient heat transfer and better compressor volumetric efficiency
- Compatible with inverter systems – R-410A refrigerant properties are well-matched to the variable-speed operating conditions of inverter-driven compressors
