Fujitsu General America Inc. has expanded its Airstage™ V-II VRF equipment line of VRF heat pumps with enhanced capabilities and operational efficiencies. The latest series now includes 6-, 8-, and 10-ton condensers, helping to reduce the number of condensers in certain configurations.
Quantech™ has expanded its line of QTC3 Air-Cooled Scroll Chillers up to 200 tons. The company says its new QTC3205 offers a more cost competitive solution to 200-ton opportunities without sacrificing size, quality, and efficiency.
Greenheck now offers low sound condenser fans as a standard offering on its Model RV and RVE pre-engineered packaged rooftop ventilation systems. Condenser fan noise levels can be a challenge with air-cooled packaged rooftop equipment installations.
SPX Cooling Technologies, Inc. has introduced the Recold Vector™ Adiabatic Cooling System, for halocarbon refrigerant condensing or CO2 gas cooling applications in supermarket refrigeration systems. According to the company, the Recold Vector provides lower energy usage and a smaller footprint than an air-cooled condenser and up to 60% or more reduction in site water usage compared to an evaporative condenser. Designed as a once-through system, the Recold Vector Adiabatic Cooling System minimizes water treatment requirements.
The CoilPro CC-400HF from Goodway provides a solution to cleaning thick evaporator and condenser coils. According to the company, there is either too much pressure that damages coils and fins or too little water volume to get through the thick coils.
The Windows-based Refrigerant Piping Design program determines the minimum pipe size required to deliver refrigerant between the compressor, condenser, and evaporator within specified pressure loss limits.
