Daikin
Sanhua enhanced pressure transmitter YCQ range has many new models suitable for all
the main applications and refrigerants including A2L and R744. This pressure transmitter is designed for a reliable and safe installation in sub-critical and transcritical R744 systems. The new range of pressure transmitter includes models with a design pressure (PS) of 90bar (suitable for all the sub-critical positions) and models with a PS of 150bar for trans-critical installations. From the new range, can be selected ratiometric models with output signal in volts or models with a current signal 4-20mA; almost all the YCQx models guarantee a full compatibility with the Sanhua EEV Controller SEC61x and the possibility to complete the full Sanhua solution for the management of the DPF/LPF uni-polar stepper valves.
Sanhua has also extended the electronic expansion valve ranges LPF and DPF with: DPF-R for CO2 LPF-D for CO2
with max pressure = 140 bar with max pressure = 60 bar
LPF series is extended with new sizes LPF30 & LPF32 which use the same coils PQ-M24.
Electronic expansion valves LPF and DPF-R are compatible with Sanhua Electronic Solution: SEC Controller with advanced PID algorithm, Pressure Transmitter YCQ with features like IP67 and Electronic Expansion Valves. Sanhua range for R744/CO2
Strict sound regulations typically apply in inner-city or residential areas where buildings are built closer together. This means that choosing highly-effi cient HVAC equipment to decarbonise the premises might pose challenges to sound regulations. The latest-generation commercial heat pumps are already designed for quiet operation, however for sound-sensitive projects, this new low-sound enclosure further reduces sound power levels by up to 10 dB(A). Additional calculations of sound, capacity or effi ciency are not needed since all essential values are factory measured. Available from end of May, the new Daikin sound enclosure specifi cally designed and tested for Sky Air Alpha-series, Sky Air Advance-series and VRV 5 S-series outdoor units reduces the sound power level by up to 10 dB(A). The Daikin sound enclosure has a highly aesthetic fi nishing and a smooth surface. An anthracite colour (RAL 7016) underlines its unobtrusive looks. Its tailor-made design fi ts our outdoor units perfectly and keeps dimensions to a minimum. Daikin sound enclosures off er a solution specifi cally designed for the low height Daikin Sky Air and VRV heat pumps. Thoroughly factory-tested sound power (ISO 3744), effi ciency and capacity guarantee fl awless system performance. This makes it possible to determine in advance how the installed system will operate. It also simplifi es the layout and planning because separate calculations are not required.

Systemair
Eurovent Certifi cation is set to launch the Energy Effi ciency Classes for Summer Application (EECS) label for air handling units (AHUs), which includes cooling and accommodates warmer weather conditions. The label will be made mandatory from September 2021. Systemair is fully prepared to provide the summer label for its entire range of Eurovent-certifi ed AHUs. Customers will be given the option to print the extra label through the online selection tools by June. The Eurovent Certifi cation summer label uses the ASHRAE climate
database to obtain realistic climate conditions. Customers can select their location or the closest fi xed city available to get the suitable options in the AHU confi gurators of Systemair and Menerga. The calculations have considered the temperature and humidity at the highest level, in view of its impact on the cooling rate. Systemair has played an active role in initiating discussions surrounding
includes a range of components for
sub-critical applications and trans-critical applications, like ball valves, check valves and others.
