Expanded Quantech QTC3 Air-Cooled Scroll Chillers
Johnson Controls expands its line of Quantech QTC3 air-cooled scroll chillers with two models offering a smaller footprint and increased efficiency — the 40T and 50T; the line is expanded from 40 to 230 tons. They are outfitted with brazed-plate evaporators and microchannel condensers, allowing for more efficient heat transfer. The QTC3 scroll compressors include two independent circuits for partial redundancy. Includes zero-ODP HFC-410A refrigerant and up to 50 percent less refrigerant charge, and full-load and part-load efficiencies that meet or exceed ASHRAE standards. They also contain native building automation system communications, including BACnet, Modbus and N2.
AquaSnap 30MPA Water-Cooled/Condenser-Less Liquid Chiller
Carrier’s AquaSnap 30MPA liquid condenser-less chillers offers a flexible modular design, compact size and user-friendly controls for industrial applications. The units are designed for use with a remote condenser and include a liquid line isolation valve, liquid line solenoid valve and have a nitrogen holding charge. They may be connected to an air-cooled, evaporative condenser(s) or even liquid condenser(s). Has the modular capability to install up to eight modules together to reach capacities up to 560 tons. ComfortLink controls provide chilled water temperature reset, compressor wear minimization and protection, as well as temperature, pressure and other valuable unit operating information. The energy management module minimizes chiller energy consumption.

YZ Magnetic-Bearing Centrifugal Chiller
York extends the capacity range of its YZ magnetic-bearing centrifugal chiller to include chillers beyond up to 1,350 tons (4747 kW) of refrigeration. The unit uses an integral, variable-speed drive and advanced magnetic-bearing technology that features a single moving assembly suspended in a magnetic field that does not require lubrication. This technology requires 80 percent fewer moving parts than traditional oil or refrigerant-lubricated drivelines. The optimized single-stage design provides real-world energy efficiency.
Compact Micro-Channel Chiller Line
KKT Chillers’ compact chiller line offers micro-channel technology, EC Blue Owlet ventilators, electronic injection valves, high-efficiency cooling agents and digital data management with minimum space requirements. Low logistic costs due to minimized refrigerant filling (up to 100kW <12kg). Provides sensory measuring of all relevant process variables and field bus connection with different protocols. Up to 50-percent less footprint due to micro-channel technology and high efficiency refrigerant R410A. High operation comfort due to user-friendly, plaintext display with intuitive menu navigation. A wide range of applications is available due to the variety of additional options and accessories.
Agility Water-Cooled Centrifugal Chiller
Trane introduces the Agility water-cooled centrifugal chiller product line for space-limited commercial building retrofits. It is a redesigned chiller in the 175- to 425-ton range with a new and different compressor and heat exchanger. It uses next-generation, high-efficiency evaporators that decrease size by 25% and total chiller refrigerant charge by up to 25%. Part of Ingersoll Rand’s EcoWise portfolio, Agility chillers are design-optimized with next-generation, low-global-warming potential refrigerant R-513A as well as current generation refrigerant option R-134A.
Iceman Micro Series Portable Chillers
Mokon’s Iceman Micro Series portable chillers are available in air-cooled and water-cooled condensing styles, both with cooling capacities of 1/4 or 1/3 ton. The air-cooled design uses an air-cooled fin and tube condenser and is ideal for applications where cooling water supplies are inadequate or of poor quality. The water-cooled models use a tube-in-tube water-cooled condenser, primarily for installations where chilled water is required but existing cooling water supplies are not cold enough or ambient air temperatures are of a concern. The compact, table-top size portable is ideal for laboratory applications, laser cooling, micro-molding and other industrial applications.
Industrial On-Demand Water Heaters
Leslie Controls’ Constantemp steam-water heater is a completely pre-piped system, supplied with properly sized accessories. Its central component is its feed-forward blending valve, activated by a differential pressure sensing head. With accuracy of ± 3° F, the unit is available for flows up to 120 gal. per minute and temperatures adjustable from 105° F to 180° F. No storage tank is required and the water heater fits through standard doorways. Available in either single or double-wall exchanger models, options include skid-mounting, a recirculation kit and an automatic descaler, as well as an insulated cover and pressure gradient monitor.

Elite EL15XP1 Single-Stage Heat Pump
The Elite EL15XP1 single-stage heat pump from Lennox is a high-efficiency, single-stage heat pump offering up to 16 SEER and an HSPF rating of 9.00. Designed for smart energy use, the Quantum Coil uses proprietary aluminum alloy tube and fins for corrosion resistance, including corrosion caused by outdoor environmental forces such as salt air, and indoor corrosive agents, such as volatile organic compounds. Units weigh less, making installations quicker and safer for dealers. The precision-engineered scroll compressor, with its sound-dampening system, provides low noise levels and durability for homeowners.
Vectorworks 2019 Service Pack 3
Vectorworks’ Service Pack 3 release has three new features. Designers can now enjoy a new live-sync rendering connection that allows them to perform real-time rendering while making design changes in Vectorworks software with the LiveSync plug-in, developed by Lumion. Designers with an active Vectorworks Service Select membership can use Vectorworks Cloud Services to generate presentations of designs with an intuitive drag-and-drop interface. Presentations include interactive, 360-rendered panoramas that can be linked together. And a new file format called My Virtual Rig creates a two-way connection between planning, previz and console systems that implement the support needed for a seamless workflow.
