This portable industrial water chiller provides closed-loop chilled water for equipment that must be cooled with liquid rather than air, in installations where a fixed chiller is not practical. The unit is built on a caster-mounted frame with carry handles, allowing it to be moved between workstations, moved aside for maintenance, or relocated when production layout changes.
Typical applications include laser marking and welding stations, laboratory instruments, small injection moulding machines, and induction heating equipment in job shops where a single chiller serves multiple machines in sequence. The unit is self-contained with an integrated pump, 28 L tank, and refrigeration circuit, requiring only water connections and a single-phase supply at the point of use.

Commercial and Technical Advantages
Mobility without fixed installation Four casters with brakes on the front pair, plus recessed carry handles. Flexible hoses with quick-disconnect couplings allow relocation between workstations without draining the water circuit.
Single-phase supply Operates from a standard 220V single-phase supply, avoiding the three-phase distribution work normally required for industrial chillers. Suits job shops and laboratories where three-phase power is not available at the workstation.
Self-contained water circuit Integrated pump, tank, and strainer. Only supply and return hoses and a power lead are required. No external tank, pump skid, or pipework installation at the point of use.
Quick-disconnect hose couplings Self-sealing quick-disconnect fittings on supply and return allow the unit to be disconnected from equipment without draining, and reconnected at another workstation with minimal water loss.
Protection and alarm suite Alarms for low water level, low flow, high and low refrigerant pressure, compressor overload, and over-temperature. Dry-contact alarm relay for connection to the equipment interlock.
Simple control interface Digital controller with setpoint display and alarm indication. Optional Modbus RTU communication where the unit is to be monitored from a central system rather than operated locally.

Deployment Contexts
01 Job shops and fabrication cells Laser welding, marking, and cutting stations where a single chiller serves several machines in sequence, moved between them as production demands change.
02 Laboratories and test benches Analytical instruments and test rigs where cooling is needed temporarily, or where equipment is reconfigured and the chiller must move with the experiment.
03 Temporary and seasonal production Additional moulding machines, induction heaters, or vacuum pumps brought online for a production campaign, where a fixed chiller installation is not justified.
04 Facilities without three-phase power Small workshops, laboratories, and educational facilities where only single-phase power is available at the workstation and a three-phase chiller installation would require distribution changes.
Selection and Installation Notes
Capacity at operating temperature Capacity falls as water setpoint decreases. Select on capacity at the actual operating temperature: 5.0 kW at 25°C water, 3.5 kW at 10°C water. The nominal rating should not be used for selection where the process runs below 20°C.
Hose length and pump head Standard hoses are supplied at 2 m. Where the workstation is further away, confirm that the additional pressure drop remains within the pump's available head at the required flow rate. Longer runs may require larger bore hose.
Floor and access At 68 kg on four casters, the unit requires a level floor suitable for rolling. Confirm door widths and lift capacity where the unit will be moved between rooms or floors. Casters are 75mm diameter and suit smooth floors; rough surfaces require a pallet truck.
Heat rejection in the workspace The condenser rejects the full cooling load plus compressor power to the surrounding air. A unit operating at full load in a small enclosed room will raise room temperature. Provide ventilation or locate the unit where the rejected heat can dissipate.
Water quality and freezing Use demineralised water where local hardness exceeds 200 ppm. Where the unit is stored in an unheated area, drain the water circuit or add glycol; the standard configuration has no frost protection and the tank and pump are not drain-protected.
Maintenance interval Strainer cleaning every 3 months. Condenser coil cleaning quarterly where the unit operates in a dusty shop. Water change annually. Refrigerant charge and pressure switch verification annually. Caster inspection every 6 months.
Procurement FAQ
Yes, within the same floor level on a smooth surface. Quick-disconnect couplings allow the unit to be disconnected from equipment without draining. For movement between floors or over rough surfaces, drain the tank first to reduce weight and avoid spillage, and use a pallet truck rather than the casters.
Standard hoses are 2 m. The pump provides 0.25 MPa at 22 L/min; extension beyond 5 m total hose length may reduce flow below the requirement of the equipment. Provide the required flow rate and distance for confirmation of pump suitability, or specify the higher-head pump option.
No. The enclosure is rated IP21 for indoor use and is not protected against rain or dust ingress. For outdoor installation, specify the weatherproof variant or locate the unit in a sheltered area. Note that the water circuit has no frost protection in the standard configuration.
A float switch in the tank detects low level and stops the compressor to protect the pump and evaporator. An alarm is raised and the dry-contact relay changes state. The unit resumes operation once the tank is refilled and the alarm is reset, subject to the configured restart delay.
Dimensional drawing, wiring diagram, capacity curve against water temperature, pump curve, refrigerant data sheet, installation and commissioning checklist, and declaration of conformity under LVD and EMC directives. Pressure test record for the refrigeration circuit is supplied.
Standard warranty is 24 months from commissioning or 30 months from shipment. Compressor coverage extends to 60 months. Pump seals, strainer elements, hoses, and casters are consumable items. Service parts including compressors, pumps, controllers, and casters are held for a minimum of 10 years.
