Hydraulic module Integrated pump, buffer tank, Y-strainer, flow switch, fill and drain points, and pressure gauges on the unit frame. Factory assembled and pressure tested with the water circuit complete before delivery.
Compliance CE marked under LVD 2014/35/EU and EMC 2014/30/EU. Refrigerant data sheet per EN 378. RoHS 2 compliant. Declaration of conformity supplied with each unit.
This air cooled chiller with hydraulic pump is supplied as an integrated unit combining the refrigeration circuit, air-cooled condenser, circulation pump, and buffer tank on a single frame. The arrangement is intended for installations where the cooling equipment must be a self-contained package: the plant room contains the chiller, and the complete water circuit is already assembled and tested rather than being built up on site from separate components.
The configuration suits process cooling where a buffer volume is required to absorb load variation, and where the water circuit is not part of an existing central plant with its own pumps. Site work reduces to positioning the unit, connecting supply and return water lines, and making the power connection.
Integrated Hydraulic Circuit
Circulation pump Centrifugal pump with mechanical seal, mounted on the frame and wired to the control panel. Flow 280 L/min at 0.40 MPa. High-head option available where the circuit requires greater pressure.
Buffer tank 400 L insulated tank with fill, drain, and vent points on the unit exterior, plus level sight glass. Buffer volume absorbs load swings and reduces compressor cycling.
Strainer and flow switch Y-strainer on the pump suction with a serviceable element. Flow switch interlocked to the compressor, so cooling cannot run without confirmed flow. Both accessible from the front panel.
Air-cooled condenser Condenser coil with EC fans mounted on the unit frame. Fan speed controlled from head pressure. Coil face accessible from the unit exterior for cleaning without removing panels.
Commercial and Technical Advantages
Complete package, one supplier Chiller, condenser, pump, and tank supplied and tested as one unit. Performance figures for capacity, flow, and head refer to the complete assembly rather than components with interface assumptions left to the installer.
Reduced site scope Pump wiring, flow switch, and controls are complete from the factory. Site work is limited to water connections and power supply, which shortens the installation programme and removes interface risk between trades.
Factory pressure tested The water circuit is assembled and pressure tested before delivery, and the refrigeration circuit is charged and tested. Test records for both are supplied rather than being recorded for the first time on site.
Buffer volume for load variation The 400 L tank absorbs short-term load swings and reduces compressor start frequency. Where the process has batch or intermittent heat loads, the buffer is what prevents repeated cycling between start and stop.
Service access arranged on the frame Strainer element, flow switch, tank fill and drain, and pressure gauges are all accessible from the unit exterior. Routine water circuit maintenance does not require removing panels or disconnecting pipework.
Single monitoring interface Modbus RTU registers expose water temperatures, flow status, tank level, fan speed, pump status, and alarm codes from one set of registers. No need to integrate separate chiller and pump controllers.

Deployment Contexts
01 Process cooling without a plant room Sites where no separate plant room is available and the cooling equipment must be installed adjacent to the process with a defined footprint and a single power feed.
02 Batch and intermittent processes Moulding, extrusion, and batch mixing processes where the heat load varies through the cycle and the buffer volume prevents the compressor from cycling repeatedly.
03 Retrofit into existing circuits Facilities replacing an ageing chiller where the existing water circuit remains and the replacement must connect to the existing supply and return lines with a defined flow and head.
04 Projects with constrained site labour Installations where site labour for interconnecting separate components is limited, and where the reduced site scope of a packaged unit shortens the installation programme.
Selection and Installation Notes
Pump head against circuit The integrated pump provides 0.40 MPa at 280 L/min. Confirm that the equipment-side pressure drop plus site pipework losses remain within the available head at the required flow. Where greater head is required, specify the high-head pump at order stage.
Structural loading At 1180 kg dry and approximately 1580 kg with the tank filled, the installation position must be assessed for structural capacity. Confirm floor loading and the lifting plan before delivery. Lifting points are provided on the frame.
Airflow and heat rejection The condenser rejects the full cooling load plus compressor and pump power to the surrounding air. Ensure the installation location can dissipate this heat or provide ventilation. Maintain 600mm at the condenser inlet and 900mm at the discharge.
Water quality and freeze protection Use demineralised or softened water where local hardness exceeds 200 ppm. Where the circuit is exposed to below-zero ambient during shutdown, glycol is required and the pump and capacity should be adjusted accordingly. The unit does not protect standing water from freezing.
Power and protection A single power feed serves the chiller and pump. Dedicated 3-pole breaker sized for 172 A per phase, with cable sized accordingly. Grounding resistance ≤ 4 Ω. Confirm available supply capacity before installation.
Maintenance interval Y-strainer cleaning quarterly. Condenser coil cleaning quarterly, more frequently near trees or industrial discharge. Tank water quality check annually. Pump mechanical seal inspection every 2 years. Refrigerant charge and pressure switch verification annually.
Procurement FAQ
The hydraulic module is normally integrated with the chiller as a single package. A separate pump and tank skid can be supplied for connection to an existing chiller, where the flow and head requirements are known and the chiller has a compatible flow switch interface. Provide the existing chiller data for evaluation.
Site work is limited to positioning the unit, connecting supply and return water lines to the flanged connections, making the power connection, and filling and venting the water circuit. Pump wiring, flow switch wiring, and the interconnections between chiller and tank are completed at the factory.
Head pressure control with variable-speed EC fans is included as standard, allowing operation down to -15°C ambient. For lower ambient, the low ambient package with additional fan cycling logic and receiver sizing can be specified at order stage. Confirm the site's design minimum ambient before ordering.
Yes. A drain point is provided on the tank exterior with a hose connection. The water circuit is normally drained for transport and filled on site. For winter shutdown in unheated locations, drain the circuit or ensure glycol concentration is adequate for the lowest expected ambient.
Dimensional drawing including lifting points and maintenance clearances, wiring diagram, capacity table against water temperature, pump curve, refrigerant data sheet, Modbus register map, factory pressure test record for the water circuit, refrigeration test record, installation and commissioning checklist, and declaration of conformity under LVD and EMC directives.
Standard warranty is 24 months from commissioning or 30 months from shipment. Compressor coverage extends to 60 months. Pump mechanical seals, strainer elements, and flow switches are wear or consumable items. Service parts including compressors, EC fans, controllers, and pumps are held for a minimum of 10 years.
