RectorSeal® Corp. has introduced the Paircoil™, pre-insulated, malleable linesets designed specifically to expedite installation of ductless mini-split and conventional air-conditioning systems in North America. Paircoil is sold in 65-ft rolls of either .25 and 3/8-in-diameter; or .25 and .50-in-diameter copper liquid/suction line sizes.
Bosch Thermotechnology has launched its new LM Series water-to-water (W2W) heat pump line for new commercial and retrofit applications. The LM Series includes five models from 2 to 6 tons. They can be used in horizontal and vertical configurations depending on the application, and feature a two-speed scroll compressor and a commutated motor as standard components for efficiency and comfort. They achieve up to 32 EER part load and up to 22 EER full load.
Grundfos has introduced an expanded line of fully integrated, intelligent pumping systems. Ideally suited for new commercial HVACR applications and deep retrofits, the line now features the MLE variable speed motor in ranges from 3 to 30 HP for building services.
The new JS Series BACnet thermostat from Jackson Systems combines the power of a space-mounted equipment controller with built-in temperature and humidity. The thermostats include a wide range of factory supplied programs for the following applications: two-pipe and four-pipe fan coil units, roof top units, heat pump units and packaged and split unitary systems.
Platform 125 from Reznor offers different applications in a single platform. Three distinct models can handle a variety of commercial/industrial applications, such as makeup air, ventilation, and recirculation. Whether you need a lot of makeup air, space temperature control, or a hybrid of the two, one of the Reznor® packaged systems will offer a solution.
Schebler says its Sequence Draft Control™ (SDC) design service offers boiler and hot water heater manufacturers a complete engineered venting system. SDC is capable of maintaining the desired condensing dew point of combustion, preventing excess draft which impacts efficiency and fuel/air ratio’s – especially with high turndown modulating burners.
Mitsubishi Electric U.S. Cooling & Heating Division has made enhancements to the P-Series Hyper-Heating INVERTER (H2i®) heat pump outdoor units for light commercial applications. Featuring H2i technology, the company says its H2i P-Series boasts higher efficiency and performance with improved heating capacity at very low ambient conditions. The units Hot Start process guarantees warm air flow from the start, which is critical in cold climate conditions where heating performance truly counts. Additionally, the P-Series offers multiple fan speeds, and its humidity-reducing dry mode helps to combat excess moisture in rooms.
Taco has expanded its suction diffuser line with three new sizes: 4- by 2.5-in, 5- by 3-in, and 8- by 5-in sizes. Taco says its suction diffusers incorporate numerous features into one device that simplifies installations and reduces installation costs.
The new MagnaTherm from Laars is a 95% thermal efficiency modulating-condensing boiler or volume water heater available in 2, 3, and 4 million Btu/H sizes. MagnaTherm says it offers a 5:1 turndown, small footprint, slim vertical design with removable top section, a stainless steel heat exchanger, and multiple voltage options to match building service. Designed and made in the U.S.A, the MagnaTherm meets all ASME requirements and is AHRI certified.
A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability.
