Remote Refrigeration Units
Remote refrigeration units for cold storages, frost storages and blast freezer spaces. Air and water cooled condensers, standard & custom builds available
Our remote refrigeration units are designed to ensure reliable and efficient cooling performance in temperature-controlled environments such as food processing plants, HoReCa establishments, pharmaceutical storage areas and logistics facilities. Each unit is built with air-cooled condensers or water-cooled condensers, robust mechanical protections and field-serviceable components to simplify maintenance and minimize downtime. The product range includes cold storage, frost storage and also blast freezing. Designed in compliance with current EU environmental regulations, all models operate with approved eco-friendly refrigerants and meet the latest energy-efficiency and safety standards.
Why Remote (Split) Systems?
Remote (split) refrigeration separates the indoor evaporator from the outdoor condensing unit. This layout improves thermal management in the workspace, enables higher system uptime, and allows the condenser to operate in clean, cool ambient air—key to reliable and efficient performance.
- Proven reliability: Outdoor-mounted condensers avoid process heat and steam inside the building, reducing coil fouling and nuisance high-pressure trips. Clear service access to compressor, fan and controls also shortens maintenance time.
- Stable product temperature: Keeping the heat-rejecting side outdoors minimizes temperature spikes in prep rooms and corridors, supporting consistent cold-chain conditions.
- Higher efficiency potential: With proper controls—fan-speed regulation, floating head pressure and liquid subcooling—remote units can reduce condenser fan energy and compressor lift, improving seasonal efficiency.
- Low noise in occupied areas: Moving the condenser and its fans outside significantly lowers sound levels around the cold room, helping meet workplace comfort targets.
- Scalable & serviceable: Pipework and component layout are optimized to the site. Future capacity increases (larger condenser, different compressor) are easier versus sealed monoblocks.
- Better hygiene & safety: Eliminating hot air discharge and oil odor from production zones simplifies hygiene control and reduces cross-contamination risk.
Monoblock vs. Remote — What’s the Difference?
A monoblock integrates evaporator and condenser in one package mounted through the wall or on the ceiling. It’s quick to install and ideal for small rooms with short pipe runs. A remote (split) system separates the indoor evaporator and the outdoor condensing unit. It suits larger rooms, longer duty cycles and locations where indoor heat/noise must be minimized. Remote systems also provide greater service access and better condenser airflow for efficiency.
Remote Refrigeration Units Condenser Options
Stable condensing pressures via shell-and-tube/coaxial heat exchangers — excellent in hot or space-constrained sites.
Pros: High efficiency at elevated ambient, compact footprint, reduced outdoor noise/airflow requirements.
Best for: Pharmaceutics, urban sites with limited roof area, facilities using closed-loop or tower water.
Notes: Requires reliable water circuit and water treatment; plan for tower/chiller and water quality control.
Self-contained, finned-coil design with axial fans — fast to install and low maintenance.
Pros: Simple plumbing, lower operating costs in temperate/dry climates, easy field service.
Best for: Food processing rooms, HoReCa back-of-house, logistics hubs with outdoor roof/yard space.
Notes: Performance depends on ambient air temperature; consider noise and placement clearances.

Selection Notes
Room volume indications are calculated based on typical product loads and expected heat gains/losses under standard operating conditions. These figures are intended as planning guidance only; real performance will vary with factors such as product type and pull-down, door cycle frequency, air infiltration control, defrost strategy, ventilation patterns, and ambient conditions.
