Nidec
Nidec Leroy-Somer, a specialist in drive solutions for industrial refrigeration has launched its new Dyneo+ synchronous reluctance PM motor, ranging from 11 to 500 kW, for speeds of up to 4500 rpm. Specially designed for variable speed, this motor off ers an economic and ecological solution for the requirements of industrial refrigeration.
With its IE5 Ultra-Premium effi ciency level, Dyneo+ is said to achieve substantive energy savings in real conditions of use over the course of the cycle, at variable speed and load, as is typical with industrial refrigeration, where needs fl uctuate considerably according to season and production level. Dyneo+ motors are designed to operate exclusively with a variable frequency drive, allowing them to adapt to the speed of the machine being run and improve its performance when operating in overspeed. This provides the benefi t of additional refrigeration capacity for a given device, thereby avoiding having to start up another compressor during a production peak. Moreover, the Dyneo+ solution enables optimisation of the number of compressors for a given installation. Delivering precise speed and torque control in sensorless mode, it guarantees constant torque over extensive speed ranges, with no derating or forced ventilation.

Vert Technologies
Vert Technologies is targeting further investment to accelerate its delivery of new compressor designs for refrigeration OEMs. The Edinburgh-based company, manufacturers of a revolutionary conical rotary compressor (CRC) that is fully proven and patented, is embarking on an equity funding process to raise £3million. The investment will be used to build on the momentum of CRC with OEM refrigeration companies requiring innovative air compressor solutions to help them meet tightening environmental regulations. Vert is already working with several OEMs in the sector and the expectation is that at least one will reach volume sales or licensing stage by the end of 2021. Vert chief executive, Phil Harris, says that the investment is a critical part of bringing refrigeration designs with embedded CRC technology to the market. “This stage of funding will accelerate the delivery of the OEM specific designs we are already working on and allow us to develop a low-cost, high volume manufacturing capability that can produce the numbers of units that the OEMs require.”

cooling duty to 10kW nominal. The new condensing units feature the Copeland Scroll compressor and come complete with all necessary refrigeration controls and components. These new systems have the advantage of longer 50m pipe runs – enabling installation in the most demanding situations. Each system is supplied with appropriately sized expansion valves and fan discharge air straighteners to enhance air distribution in larger cold rooms. The Cellar Plus systems are suitable for multiple cooling applications in industries beyond pubs, bars and restaurants.
An air temperature range of 4°C to 15°C – adjusted and maintained by the electronic controller – allows product cooling in diff erent industries including fresh fruit and vegetables, fl owers, dairy products and other items requiring a temperature-controlled environment. These compact cooling systems are also ideal for pharmaceutical and medical goods storage as well as blood and vaccine storage.
The indoor cooling unit was developed specifi cally for cellar cooling. It has a robust case, can be wall or ceiling mounted and, importantly, has six fi ns per inch brewery specifi cation evaporator coils which makes it easy to clean and maintain.
