Launch of the Silver Hydrocarbon R290 Chiller range

Project Overview

Pure Thermal has launched the high-capacity Silver R290 Chiller range to the UK market.

The new Silver R290 Hydrocarbon Packaged Chiller range, manufactured by the specialist Italian company Enerblue and provided in the UK by Pure Thermal, provides nominal cooling output capacities from 250kW to 800kW with options for partial or 100% heat output options.

To mark the launch, Pure Thermal has provided two of these latest Silver Hydrocarbon R290 chillers, delivering Production & Process Cooling, to a Leading Specialist Contractor for installation within a Global Food Producers Flagship Manufacturing Site in the UK.

This installation marks the UK launch of this larger cooling capacity, high-efficiency R290 range, which is geared towards retrofit or new applications for both commercial/HVAC and industrial/process cooling applications.

Each nominally rated 800kW Natural Refrigerant Packaged Water/Glycol Chiller operates at a system temperature of -10°C with the added benefit of providing 100% of the recycled waste heat from cooling to the site heating services.

PURE EFFICIENCY | PURE SUSTAINABILITY | PURE SAVINGS

What is Silver?

A larger capacity Hydrocarbon R290 Air Cooled Package Chiller range is manufactured by Enerblue and provided by Pure Thermal as the Enerblue UK Partner Distributor.

What are the key points?

Natural Hydrocarbon Refrigerant, -10°C Output Temperature capability, Two Heat Output options with a High level of operational performance

Is this technology new for Enerblue & Pure Thermal?

Definitely not, Enerblue has been manufacturing R290 Chillers for over 10 years and can demonstrate an industry leading track record with respect to the production of Hydrocarbon Refrigerant plant

Why Hydrocarbon R290:

A practical, historically well proven and efficient Low Carbon Non F-Gas future proofed alternative to traditional Synthetic F-Gas Refrigerant Chillers suitable for the majority of Chiller applications in the UK

Key Features

  • Silver operates with Screw Compressors via Variable Speed Drive options
  • Silver is available as a Chiller or Chiller + Heat Output (recycling waste heat from cooling)
  • Silver utilises Natural Low Carbon Refrigerant R290 with GWP 3
  • Silver is suitable for both commercial and industrial applications
  • Silver provides a practical alternative to F-Gas Chillers
  • Silver is Ideal for Retrofit/Chiller replacement or new projects
  • Silver has 2 x options for delivering waste heat with high operational efficiency
  • Silver provides nominal capacities from 200kW to 800kW
  • Silver delivers output temperatures from -10°C to 18°C
  • Silver is available with extended warranty options up to 5 years subject to terms
  • Silver is supported by Pure Thermals Industrial Refrigeration Engineering Team

Application

The 2 x Chillers on this application were utilised within the manufacturing site to provide cooling for both product and process requirements.

Operating at -10°C Cooling and 40°C Heating the 2 x Silver 900.2 Chillers were integrated within both cooling and heating systems via balancing tanks, which were then distributed to the site wide services.

Technical Overview

The Silver range provides the latest R290 Technology with SEER & SEPR compliance and is optimised for both Process/Production and Air conditioning/HVAC applications.

On this application, the model 900.2 was utilised with Low Temperature Cooling output and 100% Recycled Waste Heat output capability:

Summary

The Silver R290 Chillers provided an ideal solution for this project and definitely showed that applying Hydrocarbon R290 Chillers within demanding applications is both an efficient and low carbon practical option when considering retrofit or new applications.

This project delivers a great example of a Silver Hydrocarbon R290 ‘Larger Capacity’ Chillers delivering high performance and resilience, providing a non F-Gas alternative to traditional Synthetic Refrigerant Chillers.

The credentials of the Silver range ensure that designers/specifiers have significant flexibility to apply these high specification Chillers within the most demanding applications, whether in Cooling only or Cooling + Heating modes.

The launch of the Silver Hydrocarbon R290 Chiller range has been featured on well-regarded industry platforms, including CIBSE Journal, Cooling Post, elemental LONDON, and ACR Journal, highlighting Pure Thermal’s innovative contribution to sustainable cooling solutions.
