What Our Quick Freezing Lines Are Freezing Every Day

Quick freezing equipment is specified per product, not per catalogue page. These are the six product groups our spiral, fluidized and tunnel freezers run on most often.

Meat & Poultry

Portions, diced meat and marinated products frozen individually for retail packing, food service and further processing.

Seafood & Aquatic Products

Shrimp, fillets, squid and shellfish — fluidized beds for loose pieces, spirals for glazed and trayed product.

Fruit & Vegetables

Peas, sweetcorn, berries, mango and diced vegetables frozen at harvest, with pieces that stay free-flowing in the bag.

Prepared Foods & Bakery

Dumplings, patties, noodles, pastry and ready meals frozen on trays or belts without sticking or deformation.

Dairy & Beverage Ingredients

Cream, cheese, fruit preparations and purees frozen for storage, transport and later processing.

Cold Chain & Distribution

Freezing lines feeding cold rooms and distribution centres, matched to the refrigeration plant you already run.

New line, replacement or capacity upgrade: we supply freezing equipment for new factory lines, ageing freezer replacement, and parallel-system expansion — matched to your existing plant, refrigerant and control scheme.

Seven Reasons Buyers Standardise on These Freezing Lines

The specification decisions that decide whether a freezer holds its capacity through a full shift — and whether your service team can keep it running for a decade.

Compressor Brand of Your Choice

Run the compressor your market already services. 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

Belt speed, air temperature, defrost cycles and alarms on one touchscreen, with RS485 and WiFi remote monitoring so faults are diagnosed remotely.

Buyer benefit Fewer site visits and faster troubleshooting for your service team.

Economizer on Low-Temperature Builds

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

Buyer benefit More usable capacity per kW at the duty points that decide throughput.

Pre-Assembled Modular Construction

Panels, evaporators, belt and controls are assembled and tested as modules before shipment, cutting site installation hours and shortening the project schedule.

Buyer benefit Faster installation, fewer site interfaces, quicker 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 line stoppages.

Buyer benefit Protects the most expensive component — and your production schedule.

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 platform, several export markets — simpler stock planning.

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.

Quick Freezer Buying Guide: Answers for Distributors & Procurement Teams

Practical answers on platform choice, capacity, refrigerants, hygiene and after-sales. If your question is not here, our engineers will answer it directly.

Q01

How do we choose between a spiral, fluidized bed and tunnel freezer?

Choose by product and throughput. Spiral freezers give a long dwell time in a small footprint and suit large pieces, trayed and glazed goods. Fluidized beds are for loose, free-flowing pieces such as peas, corn, berries and shrimp that must stay separate. Tunnel freezers handle high volumes of cartons, blocks and large pieces with the simplest loading. Many plants run two platforms side by side — we will size both and compare.

Q02

What freezing capacity can you supply?

The IQF spiral series runs from 500 kg/h (QT-500) to 3,000 kg/h (QT-3000), with refrigeration capacity from 85 kW to 415 kW at a +25 °C to -18 °C duty. Fluidized bed and tunnel lines are sized individually. Give us the product, piece size and target output and we return a selection calculation.

Q03

Can the freezer work with the refrigeration plant we already have?

Yes. We can supply the freezer with its evaporators and controls only, so your existing condensing unit or screw package carries the load — or we quote a complete system including compressor, condenser and controls. Refrigerant, suction temperature and defrost method are matched to your plant before the order is confirmed.

Q04

Which refrigerants and voltages are available?

R507, R404A, R448A and R449A are all available, and units can be configured for low-GWP refrigerants to meet EU F-Gas requirements. The platform uses a wide-voltage design with 50 Hz and 60 Hz builds for European, African, Middle Eastern and Southeast Asian grids.

Q05

How is hygiene and cleaning handled?

Product-contact belts are 304 food-grade stainless mesh, panels are insulated and sealed for washdown, and an optional CIP automatic cleaning system can be specified to meet food-safety production standards. Belt width, layer count and layer spacing are configurable so the machine can be opened and cleaned quickly between products.

Q06

Do you support installation and commissioning?

Freezers ship as pre-assembled modules with a GA drawing, piping and wiring documentation, and a commissioning checklist. Our engineers support installation by remote session or video walk-through, and site supervision can be quoted with the order for first-time lines.

Q07

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.
