Kaltra Innovativtechnik, a Germany-based cooling specialist, today has released the new CNM Series air-cooled condensers intended for use with various HFC and HFO refrigerants. Thank microchannel condenser coils, introduced condensers have a 25% smaller footprint and 20% less weight in comparison to the previous generation. New condensers are equipped with high-performance fans with EC motors as a standard.
Air-based free cooling uses low-temperature ambient air as a cooling medium for chilled water systems, thus providing significant opportunities to generate energy savings. The more time the chilled water system can operate in the free cooling mode, the higher the energy savings it can deliver.
Kaltra Innovativtechnik, a Germany-based provider of innovative thermal management technologies and advanced cooling equipment, today released the Lambda DX/DXU family of feature-rich, high-end direct expansion (DX) precision air conditioners with innovative microchannel evaporators and dual refrigerant circuit amongst many of its features.
Kaltra Innovativtechnik, a Germany-based cooling specialist, has launched its chilled water rack-based cooling solution intended for use in high-density data center applications. The development of the In-Rack solution is in response to growing demand for high-density cooling solutions from the data center sector for energy savings and reduction in carbon emissions.
Jumbo Cooler fluid coolers are intended for cooling process water in industrial, commercial, and free cooling applications, and features the benefits of evaporative cooling with water recirculation, thus minimizing energy and water consumption and offer increasing free cooling hours.
Jumbo Cooler units are equipped with evaporative pads wetted via the water distribution system to pre-cool the air before passing through the heat exchanger coils. This increases the amount of heat the air can extract from the coil and, in turn, increases the cooling capacity of the unit.
The HVAC and process industries are making a transition to microchannel heat exchangers. This is evidenced by the extensive use of microchannel condensers by major HVAC manufacturers and many smaller OEMs manufacturing cooling and refrigeration equipment. Significant energy efficiency improvements drive the trend, the need for smaller equipment footprints and weight, conversion to lower GWP refrigerants, and the ongoing rise in the cost of copper.
Microchannel coils are becoming quite popular as an alternative to bulky finned tube heat exchangers. For the desired capacity, microchannel coils are smaller in size resulting in less refrigerant charge in the system, offer higher heat transfer performance, and lower weight. However, until now, microchannel coils used only to a very limited extent in HVAC units exposed to freezing conditions like heat pumps.
The efficiency of air-cooled chiller is dictated by the condensing temperature, which may be decreased with increasing heat transfer performance of the condensing coil. Microchannel heat exchangers have become popular in chiller applications due to better thermo-hydraulic characteristics in comparison to conventional finned tube heat exchanger designs. The most straightforward way to improve heat exchanger performance is to increase its face area by combining two microchannel coils in V form.

Although not traditionally used in industrial process applications, microchannel designs may offer advantages over traditional coil technologies in most process cooling applications. Long considered a coil technology primarily used in commercial and residential air-conditioning, microchannel coils are being used by more manufacturers who have discovered how they can improve process cooling applications.

I vote for fix. Anytime you can fix a condenser as opposed to replacing it, is a good day for all in the repair business. Less time = more money. Customers are happier and all around better vibe. Replacement of perfectly good coil makes no sense. Instead make the fix in less than 5 minutes with a propane torch and a few simple instruments all HVAC techs have on hand.
Approximately 10% of heat exchanger failures are connected with leaks caused by formicary corrosion. Organic compounds remain on copper tubes during manufacturing and fabrication of the HVAC equipment, are able to advance to formicary corrosion only with the simultaneous presence of moisture, oxygen, and acids.

Aluminum coils are here to stay. Not only have they been applied successfully for years by Kaltra in their spiney fin condenser coils, they have also been used for years as evaporator coils in refrigerators.
Since the introduction of the next generation all-aluminum microchannel coils, their acceptance in the process and HVAC industries has been nothing short of remarkable! The microchannel coil advantages are the future and rapidly becoming the norm because of the many benefits they provide in new HVAC equipment.
Evaporative cooling takes advantage of using water for humidification of warm and dry air and leads to significant energy savings in data center applications.
Field tests for evaluating microchannel heat exchangers with variable fin pitch (VFP-MCHE) performance have been started this week. VFP-MCHE design features variable fin pitches and dimensions, tube geometries, port shapes, and the location of fins and tubes within the same heat exchanger core.
Kaltra offers a full range of comprehensive raised floor solutions specifically designed for use in commercial buildings, data centers, clean rooms, and industrial facilities where strength and durability are critical.
The Lightstream Turbo chiller family has been designed with attention to every detail to maximize operational reliability. It is ideally suited to the requirements of mission-critical applications like data centers, telecom facilities and clean rooms, and in every area where reliability is a crucial factor.
Due to its excellent efficiency at part-load conditions, the Lighstream Turbo chiller is a brilliant economy solution for applications where the heat load is not constant or expected to increase.
All-aluminium microchannel heat exchanging products are now being widely used in the HVAC industry: they provide higher performance, smaller size, features and capabilities not found in traditional fin/tube heat exchangers.
With its installation experience and technical expertise, Kaltra was chosen by the customer to assist in the development of the new chilled water production plant for the LPG recovery facility at the GP2Z industrial zone, Algeria.
In line with its growth strategy, air conditioning and refrigeration specialist company Kaltra is laying the organizational foundations for further business diversification and market expansion. In addition to its existing core business areas, Kaltra has now also started in the evaporative cooling sector with its newly introduced product lines.
