FAQs

What types of refrigeration systems does Pure Cold supply?

Pure Cold supplies a wide range of chilled and frozen display cabinets, including multidecks, full-glass-door freezers, grab-and-go units, low-height convenience cases and specialist Beers, Wines & Spirits (BWS) chillers. They are available in integral, remote, and CO₂ configurations, allowing us to meet the needs of everything from small convenience stores to large supermarkets and forecourts.

Integral (self-contained) units house the refrigeration system inside the cabinet. They’re quick to install, don’t require plant rooms or pipework, and are ideal for convenience stores, forecourts and refurbishments.

Remote systems connect to an external pack or condensing unit. They reduce heat and noise inside the store and suit larger formats or stores with existing plant space.

Pure Cold supplies both, and we’re happy to discuss the options with you.

It depends on your store size, existing services, heat-load, layout, and energy strategy.
For example:

  • Small stores often benefit from all-integral solutions.
  • Larger stores may use remote CO₂ systems for maximum efficiency.
  • Many estates use hybrid setups, balancing practicality and performance.
    Pure Cold assesses each site and provides a tailored recommendation.

Yes. It’s one of our core strengths. We engineer low-height, compact-footprint cabinets – including 2m-high multidecks, sub-1 kW extraction cases, and full-glass-door freezers designed to line up perfectly with medium-temperature cases — making them ideal for convenience store layouts and forecourts.

Pure Cold specialises in low-GWP refrigerants, including:

  • CO₂ (R744) for remote systems
  • R290 and R1270 hydrocarbons for integral and plug-in cabinets
    These refrigerants are efficient, widely supported in the UK, and fully compliant with future F-Gas regulations.

CO₂ systems deliver:

  • Extremely low GWP (1)
  • Strong energy performance
  • High-cooling capacity suitable for busy convenience stores
  • Excellent future compliance
    They’re becoming the standard for supermarkets and increasingly for forecourts and small-format retail. Pure Cold has engineered cases specifically optimised for CO₂ DX performance.

A2L refrigerants are mildly flammable, low-GWP alternatives to traditional HFCs.
They offer strong energy performance and F-Gas compliance. Pure Cold builds A2L-ready cabinet ranges for retailers who want to future-proof their stores while keeping options flexible.

Yes. We design all equipment around natural refrigerants and next-generation low-GWP alternatives. This ensures long-term compliance with the F-Gas phase-down — including restrictions affecting high-GWP refrigerants in systems above key thresholds.

CFD (Computational Fluid Dynamics) is an airflow-modelling technique used in motorsport and aerodynamics.
Pure Cold uses CFD to optimise:

  • Airflow stability
  • Temperature consistency
  • Fan and coil placement
  • Energy performance
    This engineering approach is a key reason our cases achieve such low running costs.

Yes. We supply equipment specifically designed for small footprints, low ceilings and tight access – including petrol forecourts, kiosk formats and urban convenience stores.
Our installations at Tesco Express, One Stop and petrol forecourt operators such as MFG demonstrate this capability.

Absolutely. Many retailers have bespoke or modified Pure Cold cases created specifically for their store layouts, merchandising requirements and energy strategies.

Yes, we offer a fully managed, end-to-end service. Once the cases have been agreed, our experienced teams deliver high-quality, compliant installations on time and with minimal disruption. In addition, we offer:

  • Health and safety compliant installations to industry standards
  • Pre-site planning to ensure smooth delivery and setup
  • Flexible scheduling for your convenience
  • Testing and handover plus operator training

Our sister company – Pure Cold Solutions – is our ‘go to’ for the installation of remote refrigeration cabinets, air conditioning units and cold rooms, backed by a fleet of 18 fully equipped vans.

CO₂ and hydrocarbons are now the industry standard for supermarkets and convenience stores. Pure Cold systems are engineered for durability, with readily available parts and proven temperature performance.

Maintenance depends on system type (integral or remote), but typically includes regular cleaning, filter checks and temperature validation.
We work with national refrigeration contractors who provide full-service support.

Yes. All Pure Cold cabinets meet UK safety standards for natural refrigerants and include built-in safety and leak-prevention measures. Our systems adhere to all UK certifications and compliance standards. Hydrocarbon charges are carefully controlled to remain compliant with applicable limits.

Yes. Pure Cold has delivered large multi-site programmes for national retailers.
We provide consistent cabinet design, reliable production capacity and long-term partnership support.

By focusing on:

  • CO₂
  • Hydrocarbons
  • A2L-ready architecture
    Pure Cold helps retailers transition away from legacy refrigerants and stay ahead of changing F-Gas requirements.

Yes. For bespoke designs or new technologies, we can support pilot installations, prototype testing and in-store monitoring.

Our experienced installation teams are located across the UK so we’re never far away. We also have an approved and vetted sub-contractor installation base throughout the UK and all approved sub-contract installation teams are regularly audited.

Our office hours are Monday to Friday from 9am to 5.30pm. For emergencies (?) please contact our 24/7 support line?
