Round modular remote condenser

CMR is the innovative modular remote condenser with round microchannel heat exchangers provided by Althermo. It has been designed to meet a demanding market which is increasingly focused on the reduction of the refrigerant charge, on the constant optimization of installation space and on the reduction of delivery times.

Thanks to its innovative configuration, the CMR remote condenser allows to eliminate many limits that can be found with traditional condensers. The modular construction allows incomparable installation flexibility. The CMR modules can indeed be moved and installed with remarkable savings in logistic costs. Delivery times are dramatically reduced as well, down to 3 working days.

The CMR condenser can be equipped with 800 mm or 910 mm EC fans and speed regulator, and the microchannel coil is treated with protective epoxy coating. In addition to this, the internal volume of the microchannel coil is 60% lower than common round tube plate fin heat exchangers with the same capacity.

For special applications in highly corrosive environments, it can be supplied with an AISI 316 grade stainless steel frame and coils coated with ElectroFin which guarantees C5M rating for highest corrosion resistance

Intelligent adiabatic system

Having analyzed in depth all the pros and cons of the adiabatic systems on the market, Althermo designed INTELLIBATIC, an adiabatic system that combines all the benefits of a PADS system and eliminates its sole limitation. This led to the creation of the adiabatic system designed for Althermo modular machines which, by integrating AOP System technology with an innovative management software, gives Althermo dry coolers and modular remote condensers the highest overall efficiency compared to any other machine on the market.

Here again, the reason is simple. There are three types of adiabatic systems on the market which differ greatly from one another in terms of efficiency, water consumption, and maximum operating hours per year:

  • LOWER PRESSURE SPRAY system: this is a very simple, low-cost system which sprays a fine mist of water (micro droplets) in the air sucked in by the ventilated machine. This causes the temperature of the air being sucked in to drop, increasing the delta T and as a result, the performance of the ventilated machine. The limits of this system, however, derive from the fact that these micro droplets can humidify the air up to a maximum of 80% and with an“adiabatic jump” of maximum 30%. This means that, in optimal conditions, amaximum 5-degree air temperature decrease can be achieved. Moreover, the finned block must be treated because calcium deposits form on the fins during use, causing corrosion in the long term. The maximum operating period is, in fact, 150 hours per year.
  • HIGH PRESSURE SPRAY system: this system is similar to the previous one with added advantages, but more expensive. The water is atomized at high pressure, from 10 to 80 atmospheres by means of a pump. The resulting micro droplets are much smaller compared to the low pressure system (Misting effect) and the adiabatic effect is greater. An approximately 85% saturation can be achieved with about a 7 °C drop in air temperature. The limits of this system are the cost of treating the finned block, the loss of overall efficiency due to electricity consumption by the large, high pressure pump and increased noise emissions due to the addition of the pump. For this reason, the recommendation is not to exceed 200 operating hours per year for this system.
  • PADS system: this is by far the best adiabatic system in terms of performance. In this system, the water passes through and wets a plastic or cellulose panel fixed on the inlet side of the ventilated machine. The air sucked in by the ventilated machine passes through the panel and absorbs the moisture of the water, lowering the temperature. PADS systems can humidify the air up to 94-96%, decreasing air temperature by 9 °C. Moreover, since the water does not come into contact with the finned block, the latter does need any surface treatment and the system can operate for up to 8000 hours per year. The PADS system has one major limitation, however. Under the normal working conditions of a ventilated machine, there are room temperature and humidity conditions that do not require the use of an adiabatic panel or make it efficient. Indeed, under certain conditions, the system prevents the passage of water. Under these conditions, however, the fan loses load capacity unnecessarily because the panel, even though it is not sprayed with water, hinders the passage of the air intake. As a result, the fan becomes less efficient because it must consume more energy to guarantee the same capacity. To achieve a perfect system, you would have to remove the adiabatic panel whenever conditions dictated that it was not needed.

In the INTELLIBATIC system, the adiabatic pads, when they are not needed, open automatically, controlled by the electrical panel, thus allowing the device to reconfigure itself to dry conditions as efficiently as possible. For this reason, the INTELLIBATIC system is overall the most efficient adiabatic system: it“independently decides” the most efficient configuration based on the actual environmental conditions. Thanks to the recirculation system, the INTELLIBATIC system also limits water consumption to evaporation, so the water consumed is only what is transferred to the air to lower the temperature.

Automatic Openable Pads

This system, which can be used both with Dry Coolers and Remote Condensers, allows you to automatically exclude adiabatic panels from the flow of incoming air when the relative humidity conditions and the room temperature do not make it efficient to work in adiabatic mode.

EC fans
EC fans, which have been on the market for several years, represent the future due to the enormous technical and economic advantages offered by this technology, namely:

  1. Adjustment No inverter-controlled or phase-cut AC motor can go down to such a low rpm. A major advantage especially for all season processing plants and night operations.
  2. No risk of abnormal vibrations at low rpm.
  3. Direct relation, in terms of energy consumption, between the lower rpm and the containment of power used. In other words, the EC fan uses less energy when it slows down. A logical relation not fully guaranteed by AC solutions with adjustment.
  4. Average life not affected by adjustment. Unlike AC motors which, although of excellent quality, have a shortened life span if adjusted by phase cut, the adjustment, even with highly variable rates, does not affect the durability or reliability of the fan with an EC motor.
  5. A single code for two frequencies, different voltages and two markets. The EC fan ranges from 380 to 460 V, 50/60 Hz and CE certification, as well as UL-CSA.
  6. Rapid payback. The EC fan, especially on types with 800-900 mm diameters, has a rapid payback and gives a return on investment in ten years around twice its value.
  7. Less bulky electrical panel due to the elimination of the regulator.
  8. No additional cost for shielded cable.



One of the aspects that should be always taken into consideration in HVAC industry is prevention of damages and deterioration of components, even in the worst conditions. In particular, corrosion often affects heat exchangers and can lead to performance loss and failure. It is therefore very important to provide adequate protection in order to avoid or delay corrosion and its effects. Althermo can providedifferent coating solutions, according to the type and the site of installation. In fact, not every application is under high risk of corrosion and in those cases there is no need for special coatings. Instead, some environmental conditions or some types of application present high risk of corrosion that should be prevented or reduced. In such scenario consideration of environment and of application is essential to provide the more resistant solution.

Environments that put equipment under high risk of corrosion are: coastal and seaside areas, rural areas, polluted urban centers, industrial zones, desert zones. From an installation point of view, types of application with high risk of corrosion are: power stations, chemical, fuel and gas industry, waste disposal and sewage treatment industry.

For all applications and environmental conditions where standard coatings are inadequate, we at Althermo can offer a special coating treatment that provides the highest and best protection from corrosion.

This special coating is ELECTROFIN, a factory-applied electro-deposition coating process that guarantees complete heat exchanger coverage. The coil is immersed in a bath. Here the coil acts as a magnet and attracts the coating to every surface. The result is a thin, flexible, durable, corrosion-resistant coating.

Main feature of this special coating is that, whereas other coating processes fail in covering the entire surface, especially in particular structures such as microchannel or round tube plate coils, ELECTROFIN coating penetrates deep into the 100% of coil surfaces, covering all edges and filling all cracks.

In addition to this, the final stage of the ELECTROFIN coating process provides anextra UV-Resistant Topcoat: a layer is applied by spray to protect the ELECTROFIN coat from UV and ensure durability and long life to coils and microchannel.



  • 100% coverage of coil surface
  • Maximum uniformity of coating
  • No loss of operational efficiency
  • Reduction of maintenance, replacement and operating costs
  • Extension of heat exchanger’s life
  • No obstructions

Encased Electrical Panel
The EEP innovative construction system allows you to position the electrical panel inside a compartment within the machine frame. All the electrical components thus benefit from added protection from atmospheric conditions and the overall dimensions of the machine is decreased by at least 400 mm.
