Trailblazer is a new family of air cooled scroll chillers from Daikin, that provide unprecedented efficiencies and low cost of ownership. Trailblazer features reliable technology adopted from Daikin Applied’s popular AGZ chiller line, offering performance and features that promote low cost of ownership from installation throughout the course of its life cycle.
Goodman’s 2- to 5-ton GPH15M units feature a high-efficiency compressor with internal relief valve. The 4- and 5-ton units use an energy-efficient scroll compressor for two-stage heating and cooling. Features include copper tube/aluminum fin coils; liquid-line filter dryer; EEM blower motor; and a totally enclosed, permanently lubricated, condenser fan motor.
Lennox VRF (variable refrigerant flow) technology offers systems that require less space, energy and structural modification than competing systems, providing a flexible, versatile solution ideal for a wide range of buildings, workplaces, offices and retail environments. By offering a building the ability to create localized comfort with independent temperature control, VRF can help every occupant enjoy a perfectly heated, cooled and humidified area, making customization easy and efficient.
LG has expanded the air source range of its Multi-V IV VRF to include nominal 38-, 40-, and 42-ton outdoor unit models. The units will be available this spring in triple-frame configurations, with the 42-ton model being the only triple frame 42-ton VRF unit available in the U.S.
Mitsubishi Electric Hyper-Heating INVERTER (H2i) R2-Series Variable Refrigerant Flow (VRF) zoning system. It can operate at up to 100% of its rated heating capacity at temperatures down to 0F – the highest performance heating capacity at the lowest temperature in its field. The patented flash injection technology allows the H2i R2-Series to simultaneously cool and heat down to minus 4F and operate at 85% heating capacity down to minus 13F.
Rheem designed its H2AC Rooftop Unit specifically for high hot-water demand in commercial applications to deliver unprecedented levels of energy savings and efficiency by using waste heat from air conditioners to pre-heat water. Contractors installing this system can pair the rooftop unit with the Rheem Prestige Condensing Tankless Water Heater—an extremely efficient and space-saving Rheem water heating solution—to maximize savings.
Samsung sources say the DVMS is currently the world’s highest capacity single module outdoor unit on the market, at 16-tons, which they add exceeds the competition by 14 to 25%.The DVMS provides a 40% reduction in footprint while slimming down 30% in gross weight. The end-user will benefit with a space saving unit that will result in lower installed costs and greater energy savings.
Trane eFlex variable-speed compressors and fans available on Precedent™ roof top units deliver the performance building occupants need, while also delivering the efficiency building owners want. By precisely matching output to the cooling demands of the space, Trane eFlex compressors and fans operate at their fastest levels when demand is high, and modulate to slower levels when demand is less, for an ultra-high Energy Efficiency Ratio (EER, which measures efficiency at peak output) and Integrated Energy Efficiency Ratio (IEER, a measurement of efficiency at variable workloads).
Bacharach’s Monoxor Plus carbon monoxide analyzer detects and analyzes carbon monoxide for safety and source investigations in and around cooking and heating appliances. The Monoxor Plus uses exclusive B-Smart pre-calibrated CO sensor technology, to enable in-field sensor replacement and minimize instrument downtime.
Fieldpiece Instruments has introduced model SDMN6 Dual Port Manometer and Pressure Switch Tester. This dual-port manometer measures gas and static pressure and also accurately tests pressure switches by simulating a draft with an internal pump.
This year, hilmor introduced 24 new essentials to the line, including the Quick-Adjusting Tongue and Groove Plier, which simplifies grabbing ahold of hex, square or round fasteners while the jaw quickly adjusts with the press of a button.
With twice as many grooves as traditional Tongue and Groove Pliers, the simple sizing, strong hold and comfortable grip ensure guaranteed positioning and hold on the tool, while diminishing hand fatigue.
Shortridge Instruments, Inc. offers five different levels of AirData Multimeters. This line includes the entry-level CFM-88L, which reads airflow, temperature, and absolute pressure, to the more advanced meters, which also read velocity and differential pressures, including static and velocity pressures.
SMART Service Tools from Sporlan Division - Parker Hannifin are lightweight wireless sensors that sync with an app, enabling you to read, record and export system real-time pressures and temperatures. The free app automatically displays superheat and subcooling. Contractors monitor system’s performance anywhere within Bluetooth range, minimizing steps between components and equipment. Hoses are eliminated reducing charge loss. Data is easily recorded, saved and emailed providing proof of work.
Southwire now offers tools for HVAC needs. Southwire’s new line of hand tools is built for durability and reliability, boasting professional grade materials and construction. Contractors may choose from a wide selection of both hand tools and test and measurement tools, all meeting and/or exceeding the most stringent standards in the industry.
