Ammonia chillers

For a complete packaged system where deep freezing is necessary, our air-cooled ammonia chiller range, the i-Chiller Process LTn, is specifically designed for processes from -12°C down to -30°C​. With a simple plug and play installation, the i-Chiller Process LTn can be ready to use in no time at all. The unit is designed for outdoor installation, and the ultra compact, weatherproof, galvanised steel body, keeps the unit nicely contained and easy to position in most environments. The i-Chiller Process LTn delivers unrivalled reliability and safety, using the latest state of the art freezing technologies. The dual circuit, inverter driven semi-hermetic screw compressor allows for low charge ammonia refrigeration, without sacrificing freezing capacity or energy efficiency. Whether it's for frozen produce, meat, fish, fruit and vegetables, or pharmaceutical storage, these highly efficient ammonia chillers will help contribute towards your ESG targets through lowering your energy consumption by using the natural, zero global warming potential (GWP) refrigerant (R717). We will design, install, commission, and project manage bespoke turnkey solutions and provide full, tailored 24/7 maintenance and breakdown support with our fully qualified maintenance engineers. <strong>Complete packaged system</strong> Compared to most ammonia chillers, all of our units are compact and contained within a galvanised steel body which offers exceptional flexibility for ease of installation, operation, and maintenance. As a means to maintain temperature with precise control, you can pair the i-Chiller Process LTn with our cold storage units to provide the most flexible way to store your frozen produce. <strong>Energy efficient and sustainable</strong> R717 refrigerant grade ammonia is one of the most efficient refrigerants available, and perfect for organisations wanting to improve their sustainability footprint. Being a natural refrigerant, the climate friendly R717 has a zero rating for ozone depletion and global warming potential. These chillers also consume no water as part of the process. The i-Chiller Process LTn features Variable Speed Drives (VSD) installed as standard. These vary the output depending on the demands put on the system, and further improve the efficiency of your process. <strong>Safety and monitoring</strong> The i-Chiller Process LTn units are equipped with a range of safety features, including pressure sensors, temperature sensors, and automatic shut-off valves, ensuring safe and reliable operation. With a digital control panel and web interface, the unit collects performance data that can be monitored externally on any browser or mobile device.

Low GWP chillers

With environmental concerns taking centre stage in the public eye, and the decision making processes in every aspect of business, it is important to be aware of the options available to improve the sustainability of your process. Our range of low global warming potential (GWP) chillers use energy efficient designs and low GWP refrigerants to improve the sustainability of your chillers. With high tariffs being applied to high GWP refrigerants, and rising costs of energy, it also makes financial sense to consider the environmentally friendly options available. We have started the e-Mission critical initiative, dedicated to educating businesses on environmentally friendly solutions to their process and air conditioning requirements, making it the perfect partner for your next temperature control project. <strong>Our energy approach</strong> Since 1989 we have created bespoke temperature control solutions across all manufacturing, industrial, and critical process applications. With a nationwide network of highly experienced technical engineers, we will visit your site to understand your application needs, audit your facilities and potential constraints, and develop the optimum solution for your individual circumstance. We can design, install, commission, and project manage bespoke turnkey solutions and provide full, tailored, 24/7 maintenance, and breakdown support.

Planet friendly process cooling thumbnail

Planet friendly process cooling

Designed specifically for industry applications, the planet friendly i-Chillers feature the lowest global warming potential (GWP), and ozone depleting potential (ODP) refrigerants. Unlike traditional HVAC units, our i-Chiller range has been designed with process applications in mind. As such, they can operate faultlessly and maintain accurate temperature control 24/7 under highly differing, and abruptly fluctuating operating conditions. The planet friendly i-Chillers represent continuous progress in our e-Mission critical initiative. This ambition encapsulates several intrinsically linked energy-saving concepts and a range of next generation low GWP and ODP refrigerants, helping our customers to save energy, reduce costs, and lower their carbon footprint in the process. Within the planet friendly portfolio, our customers can find solutions to achieve increased productivity, high temperature control precision, and elevated product quality with highest environmental awareness. <strong>Futureproof your operation</strong> The fluorinated refrigerants phase down in the UK and Europe requires that the production of virgin fluorinated gases (HFCs) is gradually reduced, and HFC consumption is cut 79% by 2030. This makes it even more vital to make a timely transition to high efficiency refrigerants with a low GWP. <strong>R-454B Refrigerant </strong> The R454B refrigerant is a non ozone depleting HFO/HFC* blend with a GWP level of 467, the lowest among the refrigerants available today for scroll compressor technology. R454B offers 76% reduction in direct GWP impact against R410A and 34% reduction against R32 refrigerant. The chillers with R454B will deliver higher seasonal efficiency compared to R410A, offering up to 6% improvement, and offer more application flexibility compared to R-32 thanks to wider operating maps. *HFO – Hydrofluoroolefins; HFC – Hydrofluorocarbons <strong>R-290 Refrigerant</strong> The R290 is a non-toxic natural refrigerant which causes no damage to the ozone layer. It has a GWP of 3 and excellent thermodynamic properties, offering higher energy efficiency ratio (EER) versus traditional alternatives. Applying R290 allows customers to avoid carbon taxes, benefit from national incentives, and future-proof their investment as R-290 is exempt from the HFC refrigerant phase out programmes. <strong>R-717 (Ammonia) refrigerant </strong> The R717 (Ammonia or NH3) is a natural refrigerant with zero GWP and ODP. Its performance allows for deep freezing processes requiring heat transfer fluids between -12°C and -30°C.

Process chillers

Process chillers are designed and built from the ground up to be more reliable, operate within tighter specified tolerances and to be more robust for continued operation when compared to chillers designed for HVAC. Our i-Chillers are specifically designed to cope with the rigours of manufacturing and critical processes. Process chillers may cost slightly more than equivalent HVAC or comfort chillers but are significantly better value and fit for purpose in a critical process. A process chiller will deliver more accurate leaving water temperature, operate trouble free for longer, have a lower op-ex cost and a greater residual value. <strong>Chillers built for process</strong> Our range of process chillers is designed specifically for process, with features such as unique finned coil evaporators immersed inside the cold-water tank, making them less susceptible to freezing and able to cope with variable load and process fluctuations. The large integrated cold side buffer tank enables closer temperature control for process tolerance and reduces wear and tear from compressor start and stop operations. i-Chillers have high-pressure pumps as standard to cope with the more complex pipework found in process applications. Being fully enclosed in robust steel panels not only protects but creates a smaller footprint for ease of access and plug & play installation. <strong>Our approach</strong> Since 1989 we have created bespoke temperature control solutions across all manufacturing, industrial and critical process applications. With a network of highly experienced technical engineers nationwide, we will visit your site to understand your exact application needs and audit your facilities and potential constraints to develop the optimum solution for your circumstances. We can design, install, commission and project manage bespoke turnkey solutions and provide full, tailored 24/7 maintenance & breakdown support with our nationwide service & hire team.
