SPX launches new MH Fluid Cooler models
WORCESTER, UK, 16 June 2021: SPX Cooling Technologies Inc. has released details of its expanded MH Fluid Cooler line, which it said is designed to meet an even more diverse range of applications. The MH Fluid Cooler, the company said, is now available with three coil materials, each delivering its own advantages.
The most recent innovation, the MH Element Fluid Cooler, is equipped with copper coils, the company said, adding that copper offers superior corrosion resistance and improved heat transfer. Compared with traditional HDG coil fluid coolers, copper coil requires 35% less fluid volume, and the cooler operating weight is reduced by 20%, the company said. Copper is also sustainable, with a high recycle value at the end of its operational life, it added.
Other MH Fluid Coolers are available with coils of either HDG (hot dip galvanised) steel or stainless steel, the company said. HDG steel offers good thermal performance in a closed and pressurised system, it claimed. Models with stainless steel coils use larger coil surface area to achieve results and are often utilised in coastal regions and applications prone to corrosion, it said.
According to SPX, one of the most efficient closed-circuit cooling towers in its class, the MH Fluid Cooler, is a hybrid system that combines the functionality of a cooling tower and a heat exchanger. Utilising a combination of evaporative fill media and prime surface coils, the MH Fluid Cooler offers significantly improved performance over conventional non-hybrid systems, the company claimed. Compared to forced-draft products with comparable footprint, its proprietary CoolBoost technology uses up to 75% less fan energy, requires up to 35% less process fluid and reduces operating weight by 15% or more, it further claimed.
HVAC applications, SPX said, include water-source heat pumps, water-cooled VRF (variable refrigerant flow) systems, geothermal heat pumps and chillers. Industrial process cooling uses include water-cooled air compressors, injection moulding machines, induction furnaces and other machines or jacket cooling, it said.
Thermal capacities of all standard MH Fluid Coolers are independently certified by Eurovent and the Cooling Technology Institute (CTI) for performance with water, ethylene glycol solutions and propylene glycol solutions, it said, adding that the MH Fluid Cooler is backed by SPX’s five-year mechanical warranty and energy efficiencies that exceed ASHRAE Standard 90.1 requirements.
AHRI certification program expands test conditions
ARLINGTON, Virginia, 28 May 2021: The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) on May 18 announced that it is implementing a wide range of test conditions in certain of its certification programs, to help promote global energy efficiency; to suit varying global environmental conditions and regional needs; to align itself with local, regional and international regulations; and to address requirements of its members and certification program participants.
AHRI said that in addition to the standard T1 test conditions (35 degrees C outdoor dry-bulb), it has been introducing the T3 test conditions (46 degrees C outdoor dry-bulb) and T4-Kuwait (48 degrees C outdoor dry-bulb), with operability tests at 52 degrees C for a large range of “tropical” air conditioning products in the high-ambient temperature (HAT) countries of the Gulf Cooperation Council (GCC) region.
AHRI said that with T3 ratings already available for applied products, such as air-cooled and water-cooled chillers, and for direct-expansion products, such as ducted-split systems, packaged rooftop units in both residential and commercial segments, and inverter-type residential units, it continues to expand the T3 ratings to other products, such as VRFs. These actions and many others, it added, are why a growing number of entities around the world are relying on AHRI-certified products and equipment, which have provided performance assurance for more than 60 years across 40 programs and with more than 1,100 certified licensees across the globe.
The initiative’s first part, it said, is to help its GCC region, Asian, European and American members and program participants certify their tropical high-ambient products to T3 test conditions through simplified mechanisms and processes. The second part, it said, involves its outreach to regional regulators and authorities, informing them of their ability to ensure compliance to T3 conditions, if they wish to do so.
“We are confident that this dual approach directly supports the important value proposition of achieving governmental energy efficiency goals and regulatory/policy initiatives, while providing a wider range of quality equipment to the residential and commercial sectors in HAT regions,” said Khalil Issa, Managing Director, AHRI MENA. “Governments, consumers, and other entities have always had the assurance that AHRI Certified products have been tested by third-party laboratories to perform as promised, helping to ensure expected energy and cost savings for the benefit of institutional clients, end-users, consumers, and the environment. The expanded test conditions solidify that assurance and allow customers in these regions access to a wider array of quality product choices.”
AHRI said its publicly available, free Directory of Certified Product Performance not only allows consumers, contractors, and others to quickly assess whether a product is AHRI Certified or not but also enables local regulators to immediately enforce compliance by easily identifying non-compliant products.
