Description
Industrial monoblock designed for outdoor installation on the cold room wall, with easy maintenance access through hinged panels.
ADVANTAGES OF INDUSTRIAL MONOBLOCK REFRIGERATION SYSTEMS
- Energy efficiency and sustainability: Propane (R-290) is a hydrocarbon refrigerant with low environmental impact and excellent thermodynamic properties.
- Plug & Play: As self-contained units designed for direct installation, they help reduce installation time, simplify commissioning or installation.
- Reliability under demanding conditions: Designed to operate in extreme environments. A reliable solution for critical industrial applications such as food storage.
- Space-saving installation: No plant room required, optimising the available footprint.
- Low refrigerant charge and easy maintenance: Superblock range uses a reduced refrigerant charge and is designed with hinged panels for easy maintenance access.
- Modular design: Allows the system to be expanded in line with cooling demand without the need to redesign the refrigeration installation.
CONSTRUCTION
- Mounting frame for panel installation included as standard for series 4 and 5.
- Aluminium hinged condensate tray.
- 100 mm polyurethane foam insulating pad.
FANS
- Variable-speed EC condensation fan motors.
- Condensing pressure control via fan speed modulation.
- AC evaporator fans.
REFRIGERATION CIRCUIT
- Semi-hermetic compressor with capacity control, unloaded start and crankcase heater.
- Refrigeration circuit in annealed copper tubing, equipped with ATEX high- and low-pressure switches, ceramic filter drier, liquid sight glass, and factory pre-set thermostatic expansion valve.
SECURITY
- Independent IP55 electrical control panel for power and control, with residual current protection and MCB protection for each compressor, fan(s), and heaters.
- ATEX fans for continuous ventilation of the refrigeration compartment.
- Leak detector with audible and visual alarm.
- Shunt trip coil for cutting off the power supply line to electrical components located in the refrigeration compartment.
- Safety valve on the high- and low-pressure sides for common ducted discharge.
- Independent power supply for the exhaust fan and leak detector, with residual-current and thermal-magnetic protection. Flow switch supplied separately.
COIL
- Large area condensing coil, in copper pipes and aluminium fins, tropicalised for ambient temperature up to 45 ºC.
- Evaporator coil with copper tubes and aluminium fins.
