Advertorial Variable frequency drive for
brushless dc,permanent magnet and induction motor compressors
F
rimley, UK, 1st March 2022 – Controls and
Automation specialist, Carlo Gavazzihave launched arange of variable frequency drives. The RVPM range are specifically designed for HVAC applications to meet the efficiency regulations set by the standard EN14825. Minimum energy performance requirements (MEPS) for heat pumps have demanded the use of variable speed scroll compressors to meet the required performance (SCOP, SEER) levels and well-chosen components can have a decisive impact on a product’s overall efficiency. The RVPM is a variable frequency drive (VFD) for rotary and scroll compressors with permanent
magnet (PM), brushless direct current (BLDC) and induction (IM) motors. Equipped with both a sensor- less vector control (SLVC) for PM/BLDC compressors and a variable-voltage and frequency (V/f) control for IM compressors. Individual compressor models are already pre-configured, and a minimal set of parameters are required resulting in an easy and fast configuration. Designed with either a heatsink or cold plate for heat dissipation. The cold-plate version is suited
for heat pumps where installation space is limited and is equipped with various protection functions to protect the drive and the compressor during abnormal operating conditions, which can extend the lifetime of the compressor. It comes with an integrated mains filter to comply with residential EMC requirements and Modbus RTU communication enables real time status monitoring which improves efficiency and provides predictive maintenance as well as providing real-time data. Typical applications include heat pumps, chillers, commercial air-conditioning, and commercial refrigeration cabinets and are CE and UK CA certified.

Armstrong fluid technology launches single phase pumps for light-duty applications
A
rmstrong has launched a range of Design Envelope Permanent Magnet (DEPM) pumps for light- duty applications using single-phase power (200-230V). The new pump models are available in sizes from 0.25 to 1.5kW and can be installed in either horizontal or vertical piping. Compared to
conventional ECM circulators or pumps with loose drives and standard induction motors, Armstrong’s new DEPM pumps provide up to 30% operating cost savings, with increased variable speed efficiency, and the option of real-time performance monitoring and parallel pumping. A wide range of applications require light-duty recirculation and are connected to single-phase electrical power, including heating and water recirculation systems in commercial and residential buildings, groundwater loops and geothermal systems. The conventional approach for these applications has been to install a low-cost, light-duty circulator. Whilst this meets the application requirements and minimises capital costs for a project, many circulators are not repairable, and are designed for

only a few years of operation. Armstrong’s new DEPM pumps provide a number of valuable advantages. Following the design standard for commercial pumps, they are built to last and can be easily and economically repaired. Design point and setpoints can be adjusted to match on-site conditions, with a quadratic pressure control curve for maximum efficiency in variable speed applications. The pumps also incorporate a constant flow function, for maintaining a precise flow rate in recirculation applications. There is the added option for a 50:50 split of design flow, for redundancy and additional energy savings using embedded Parallel Sensorless Pump Control. Lastly, the new DEPM range incorporates intelligence and connectivity, for access to the subscription-based Pump Manager service. This service provides cloud-based analytics that support performance optimisation. Users can track pump
status and performance from a desktop or mobile device with automatic alert notifications if key parameters are exceeded. For more information on the new Armstrong DEPM range of pumps: Tel: +44 (0)8444 145 145

mith Brothers are proud to be celebrating our 125 years anniversary with origins dating back to 1897, when founder Walter Smith began to lay the foundations of what has become one of the largest independent merchants operating in the UK.
The business has transitioned significantly over the 125 years from manufacturing boilers for the shipping industry, to furnishing hundreds of mills built within Leicester and assisting with the war efforts, before finally focussing predominantly on piping and HVAC supplies as the market grew in the 1960’s. Today, SBS remains family owned with 5th generation family members working within the business,
which now consists of 17 branches and 400+ members of staff. In our 125 years, we have remained focused on our brand promise of staff, stock and service, ensuring our customers are at the forefront of every decision, whilst investing in quality.
