Chiller cold rooms for fresh produce storage

A temperature range of +2 / +10 °C, tuned precisely to your products. A positive (chiller) cold room covers the whole spectrum of fresh storage: dry-aged meat, charcuterie, cheese, fruit, vegetables and cut flowers. R290 (propane) factory pre-charged up to 30 m³.

+2 / +10 °C R290 pre-charged B2B best-seller

The chiller is the most in-demand format. It covers roughly 80% of food-trade requirements: meat, cheese, deli, fruit, vegetables, flowers and pharmaceuticals. What changes from one trade to the next is the precise set-point within the range: dry-aged meat at +2 °C, fruit at +4 °C, flowers at +6 °C, catering at +8 °C. Our electronic controller holds the temperature to within 0.5 °C.

Choosing the right temperature set-point

Fresh meat and charcuterie: 0 to +4 °C (ideally +2 °C). Mature hard cheeses: +6 to +8 °C. Soft cheeses in finishing: +4 °C. Hard fruit (apples, pears): 0 to +2 °C. Delicate fruit (berries): +2 to +4 °C. Leafy vegetables: +4 °C. Cut flowers: +4 to +6 °C. Mixed catering: +6 to +8 °C (a compromise across products). Pharmaceutical (vaccines outside −20 °C): a strict +2 to +8 °C. If you mix several product families, take the lowest compatible set-point — meat always dictates.

Humidity and air circulation

A chiller room is about more than temperature. Relative humidity matters just as much. For meat: 75-80% RH (any lower and it dries out). For fruit and leafy veg: 90-95% RH (any lower and it wilts). For flowers: 80-90% RH. Our refrigeration unit uses a stepped ceiling evaporator with gentle defrost that holds RH without aggressive cycles. Optional ultrasonic humidifier for needs above 90% RH (flowers, leafy veg).

R290 pre-charged — the chiller standard up to 30 m³

R290 (propane, GWP = 3) is our standard refrigerant across the entire chiller range ≤ 30 m³. Typical charge: 0.5 to 2.5 kg depending on capacity, below the ATEX threshold in an enclosed space. Delivered factory pre-charged: switch it on and it runs. Advantages over R134a (HFC, GWP 1430): long-term compliance (R134a is being phased out 2026-2028 under F-Gas), +10 to 15% energy efficiency, and roughly 50% cheaper refrigerant should a recharge ever be needed.

Models in this range

Compact format · 10 m³

10m3 Cold Room — Compact, Movable R290 Unit

The 10 m³ (roughly 350 cu ft) is our entry point: the most compact small cold room that still works as a genuine professional unit. It arrives pre-charged with R290, runs on a standard 230 V single-phase supply, and can be sited almost anywhere without a heavy concrete slab. A best-seller for game-hunting groups, small butchers, florists and restaurants on temporary premises.

Core of the range · 20 m³

20m3 Cold Room — The R290 Core of the Range

The 20 m³ (roughly 700 cu ft) is our best-seller. It has the capacity for a wholesale butcher, an active hunting syndicate, a mid-sized restaurant or a market garden handling post-harvest stock. Pre-charged with R290, 100 mm PIR insulation, 400 V three-phase. This is the format where the cost per m³ is at its best.

R290 pre-charge limit · 30 m³

30m3 Cold Room — The Limit of R290 Pre-Charge

30 m³ (roughly 1,060 cu ft) is the boundary of our pre-charged R290 catalogue. It is the format for farms handling post-harvest stock, caterers with large seasonal volumes, wholesale butchers and shared hunting estates. Above this point we switch to empty delivery, with the unit charged on site by a certified F-Gas engineer.

Questions fréquentes

What is the difference between a chiller and a freezer cold room?

A chiller (positive) holds a temperature above 0 °C, typically +2 to +10 °C, keeping produce fresh without freezing it. A freezer (negative) drops below zero, down to −25 °C, for long-term frozen storage. They are separate rooms — you cannot switch dynamically between the two. If you need both modes, you want a dual-temperature cold room (two zones split by an insulated partition) or two separate rooms.

How much electricity does a 20 m³ chiller cold room use?

Under standard conditions (25 °C ambient, +4 °C inside, 70% loaded, door open 10 min/h), a 20 m³ R290 room draws 180-220 kWh per month. Consumption rises in summer (up to +40%) and falls in winter. Optimise it with a thermal lobby at the entrance, a PVC strip curtain, and disciplined door use.

Can a chiller cold room be installed in full sun?

Technically yes — the unit is rated to operate in ambient temperatures up to 43 °C. But it will consume 30-40% more and stress the components. We recommend light afternoon shading (a canopy, shade sail or shade wall). Avoid a dark heat-absorbing roof: our rooms have an off-white exterior cladding (high albedo) that already helps considerably.

What happens if the R290 leaks?

A leak in a pre-charged R290 room is rare (hermetic circuit, factory-tested, silver-brazed joints). If it occurs, the integrated IR leak sensor cuts the compressor, triggers the alarm and opens forced ventilation. Propane dissipates quickly outdoors. The partner refrigeration engineer attends within 48 h to repair and recharge (covered by the 2-year warranty if the leak is not impact-related).

How much does a chiller cold room cost, and where do you deliver?

Mobile chiller rooms start at around €5,800 + VAT for a 10 m³ unit and run to about €28,000 + VAT for larger configurations, ex VAT. Price depends on volume, panel thickness and unit power. We deliver to France, Germany, Italy and Spain, with a detailed quote within 48 working hours.
