Where Our Chiller Units Are Installed

Chiller units from Xuanyuntong are specified across cold chain and industrial cooling projects — from a single produce room to a multi-room distribution centre.

Food Cold Storage & Produce Preservation

Holding rooms for fruit, vegetables, dairy and dry goods where stable temperature and airflow protect shelf life and reduce shrink.

Meat & Seafood Blast Freezing

Low-temperature packages with economizer for fast pull-down to -30 °C ~ -40 °C in freezing rooms and tunnels.

Dairy & Beverage Processing

Chilled water and DX duty for processing halls, fermentation tanks and CIP circuits that run around the clock.

Pharmaceutical Cold-Chain Warehouses

Temperature-controlled storage with PLC control, alarm outputs and audit-friendly parameter records.

Logistics & Distribution Cold Rooms

Multi-room and parallel systems for dock-side distribution centres, built for frequent door openings and fast recovery.

Chemical & Process Cooling

Low-temperature brine cooling for reactors, crystallization, pilot lines and other industrial process loads.

New build, replacement or expansion: we also supply chiller units for new cold room projects, ageing unit replacement, and parallel-system expansion or retrofit — matched to your existing pipework, refrigerant and control scheme.

Seven Reasons Distributors Standardise on These Chiller Units

The specification decisions that decide whether a chiller unit survives a decade of cold-room duty — and whether your service team can keep it running.

Compressor Brand of Your Choice

Run the compressor your market already trusts. Stable performance, low failure rate, and spare parts that are easy to source locally and globally.

Buyer benefit Semi-hermetic reciprocating, screw or scroll — open brand or brand nominated by you.

PLC + HMI with Modbus RS485 / WiFi

Full parameter access on a touchscreen panel, plus RS485 and WiFi remote monitoring so faults are diagnosed remotely instead of on site.

Buyer benefit Lower on-site maintenance cost and faster troubleshooting for your service team.

Economizer on Low-Temperature Models

Low-temperature builds add an economizer, delivering higher cooling capacity and lower power draw in -30 °C ~ -40 °C conditions.

Buyer benefit More usable capacity per kW at the duty points that matter in blast freezing.

Skid-Mounted Pre-Assembly

Piping, wiring and controls are assembled and tested on one skid before shipment, cutting site installation hours and shortening the project schedule.

Buyer benefit Fewer site interfaces, less rework, faster handover to your client.

Multiple Safety Protections

Phase-failure, high/low pressure, oil-pressure and overheat protection work together to prevent compressor burnout and unplanned downtime.

Buyer benefit Protects the most expensive component in the unit — and your warranty record.

Wide Voltage, 50 Hz / 60 Hz

Wide-voltage design with 50 Hz or 60 Hz builds, suitable for grids in Europe, Africa, the Middle East and Southeast Asia.

Buyer benefit One product platform, several export markets — simpler stock for distributors.

Low-GWP Refrigerant Ready

Units can be configured for low-GWP refrigerants to meet EU environmental and F-Gas requirements.

Buyer benefit Future-proof specifications for European dealers and tenders.

Configure the Chiller Unit to Your Duty Point

Every chiller unit we build is quoted against a specification, not a catalogue page. Send the eleven parameters below and our engineers return a matched selection, a GA drawing and a costed offer.

Parameter · what to send

Options we build to

Compressor type & brand

Send: Open type, semi-hermetic or screw; the brand you nominate

Semi-hermetic reciprocating, screw or scroll compressor — open brand or the brand specified in your market.

Cooling capacity

Send: kW / kcal/h / TR at your evaporating and condensing temperatures

Selected at your duty point and confirmed on the approved datasheet — not a catalogue guess.

Input power

Send: Available power per phase at the installation site

Matched to your supply and starting method, including part-winding or soft start where required.

Operating temperature range

Send: Room or fluid temperature, plus ambient conditions

Medium-temperature cooling down to -40 °C low-temperature freezing builds.

Refrigerant options

Send: The refrigerant approved in your market

R404A, R507A, R448A, R449A, and low-GWP alternatives on request.

Condenser type

Send: Air-cooled, water-cooled or evaporative

V/A-shaped air-cooled coil, shell-and-tube water-cooled condenser, or evaporative condenser.

Dimensions

Send: Maximum footprint and height available

Compact layouts confirmed on the GA drawing before production starts.

Unit weight

Send: Lifting capacity and roof-load limits

Declared per configuration, with lifting points positioned for standard container loading.

Noise level dB (A)

Protection class

Send: Indoor, outdoor or washdown area

IP54 or higher on request, with weatherproof enclosure options for rooftop installation.

All core parameters can be customized. Final values are confirmed on the approved datasheet and GA drawing before production — share the duty point and we will size the unit around it.

Technical guidance through commissioning and troubleshooting — by documentation, remote session or video walk-through with your engineers.

Questions Distributors Ask Before the First Order

Short, practical answers on compressor choice, OEM supply, refrigerants, voltage and after-sales. If your question is not here, our engineers will answer it directly.

Q01

Can we choose the compressor brand and model?

Yes. Compressor type and brand are open on every chiller unit we build — run the semi-hermetic, screw or scroll compressor your market already services, or nominate a brand and we will quote around it. Global spare-parts availability is part of the selection, not an afterthought.

Q02

Do you build chiller units under our own brand?

OEM and ODM supply is standard for distributors: your nameplate and logo, agreed enclosure colour, your manual language, export packing and — where needed — control logic and parameter defaults set to your service standard.

Q03

How does the PLC and remote monitoring package work?

Each unit runs a PLC with HMI touchscreen. Modbus RS485 is available as standard for BMS or SCADA integration, and a WiFi gateway can be added for remote monitoring. Your engineers can read parameters, review alarms and troubleshoot remotely instead of sending a technician to site.

Q04

Which refrigerants can the chiller units run on?

R404A, R507A, R448A and R449A are all available, and units can be configured for low-GWP refrigerants to meet EU environmental and F-Gas requirements. Tell us the refrigerant approved in your market and we will match the expansion valve, pressures and charge to it.

Q05

Can you build for 60 Hz, 440 V or 220 V single phase?

Yes. The platform uses a wide-voltage design with 50 Hz and 60 Hz builds, so the same model can be supplied for European, African, Middle Eastern and Southeast Asian grids. Voltage, phase and starting method are confirmed on the datasheet for each order.

Q06

What is the warranty, and how do we get spare parts?

Standard warranty is 12 months from shipment. Genuine factory spare parts are supplied worldwide, with technical guidance for commissioning and troubleshooting. Extended warranty can be negotiated with the order — useful when you resell into projects with a maintenance contract.
