Innovative Cooling Towers
For its HXV closed-circuit hybrid cooling tower, Baltimore Aircoil (Baltimore) earned an AHR Expo Innovation Award, grabbing the top honor in the “Cooling” category. Meanwhile, Marley Cooling Technologies (Overland Park, Kan.) showcased a “new and improved” cooling tower line featuring what it believes to be an industry first: rotomolded polyethylene UniBasin technology.
Innovative, UniqueAccepting the Innovation Award on behalf of Baltimore Aircoil (BAC) was Branislav (Branko) Korenic, Ph.D. chief engineer, who, along with Tom Carter, director of coil technology and product development for BAC, developed the HXV’s unique Combined Operation Technology. Also on hand to accept the award were Eric Kriebel, assistant product manager for closed circuit cooling Systems, and Philip Adams, marketing communications manager.
“The HXV can be a real problem solver for some of your toughest projects,” said Frank Morrison, product manager for Closed Circuit Cooling Systems. “It’s just the latest example of BAC’s leadership in evaporative cooling innovation.”
This product was conceived by BAC’s European Marketing Group and implemented by Korenic and Carter. It was designed to meet the thermal performance capability of a typical evaporative closed-circuit cooling tower for applications where plume abatement is a critical issue or where water usage is restricted.
The HXV is based on BAC’s line of FXV closed-circuit cooling towers, which the company said utilize combined flow technology to provide high heat transfer rates at low fan horsepower in a compact footprint.
The HXV adds a copper/aluminum finned dry coil above the galvanized prime surface evaporative coil and PVC wet deck surface. A three-way modulating fluid flow control valve enables the HXV to operate in any of three modes — dry/wet mode, adiabatic mode, or dry mode — depending on the heat load and ambient temperatures, explained Morrison.
Meanwhile, Marley said its innovative application of rotomolded polyethylene to the UniBasin of its new NC line of cooling towers significantly increases durability and enhances performance, “making this the most comprehensive advancement to the NC cooling tower line since the original design launch in 1968.”
Rotomolded polyethylene is frequently used for heavy-duty product applications such as fuel and chemical storage tanks and shipping containers because of its resistance to acids, chlorides, and other caustic chemicals. In addition, polyethylene is considered tough, resilient, impact-absorbent, and lightweight, plus it does not support the growth of algae, bacteria, and fungi.
“The advantages of the rotomolded polyethylene UniBasin far surpass those of the multi-piece steel basin,” said Brad Grindstaff, industry manager of Marley’s HVAC division “Our new NC line has forever redefined the HVAC cooling tower industry.”
Also new is the MX20, a compact heat exchanger specially developed for HVAC cooling duties. The company said the product’s compact size with low height makes it “ideal as a replacement heat ex-changer as a pressure breaker, condenser cooler, or thermal storage unit in existing buildings.”
“This makes it extremely environmentally friendly due to the minimum amount of materials being used in its construction and also the space taken for its installation,” said the spokesperson.
