Refrigeration

Grundfos' cooling pumps are ideal for circulating refrigerants in applications with temperatures below 0°C. Efficiently, reliably and without deviating from the set temperature.

While a standard single-stage centrifugal pump efficiently handles brine and glycol, a multistage centrifugal pump has been optimised specially to cater for more hazardous and high pressure demanding refrigerants like carbon dioxide and ammonia.

The multistage pump can be supplied with magnetic coupling (MAGdrive) or canned motor that efficiently eliminates any risk of dangerous leakage and in turn ensures perfectly safe work environments. Moreover, the ability to circulate carbon dioxide allows Grundfos' dedicated pump to contribute to a greener world. Particularly in third world countries where resources are sparse it makes sense to be able to use a natural refrigerant like carbon dioxide rather than producing costly synthetic refrigerants.

On top of our extensive line of high-quality pumps for primary refrigerants, Grundfos also offers a dedicated range of pumps for secondary refrigerants, operating flawlessly in temperatures as low as -60°C. Naturally all refrigeration solutions can be customised to match individual requirements.

 

ChallengeSolution
Secondary refrigerants require circulation at very low temperatures.Grundfos offers a special coolant pump capable of handling liquid temperatures down to -40°C.
Critical cooling processes may require that the temperature does not deviate.By applying one of Grundfos' speed-controlled pumps the temperature is held constant.
High viscosity or liquid density of the refrigerants can cause motor overload, which potentially leads to downtime.Grundfos offers oversize motors that can easily handle viscosity and density.
Installations with varying temperatures risk creating water condensation in the motor at standstill.Grundfos offers integrated motor heaters to completely avoid condensation.
Toxic or malodorous coolants like ammonia must be handled by completely reliable pumps to prevent leakage that may damage equipment or people.Grundfos offers completely leak-free pumps for hazardous media, ensuring that the liquid cannot escape its closed circuit.
Flammable coolants must be handled extremely carefully and professionally.Grundfos offers a range of pumps designed for efficient operation in explosive environments. The pumps naturally comply with the ATEX directive
Energy consumption is important to your customer.Grundfos' high-efficient E-solutions significantly reduce energy consumption by automatically adjusting pump performance to the actual need. Naturally, the E-solutions meet all international efficiency standards.
Stock management is made difficult due to the global differences in voltages and frequencies.Grundfos' E-solutions feature dual frequency and a wide voltage range, allowing you to use the same solution all over the world. Naturally, the E-solutions carry all necessary electrical approvals.

Important notes

  • Grundfos offers a wide range of pumps, which comply with the ATEX directive.
