Our close control air conditioners are suitable to be applied for air conditioning of
telecommunication offices, computer rooms, data servers, high automated offices and special
“close control” uses.
They can be used also for application into common business and tertiary environments, as for
example conference rooms, shopping centres, restaurants, libraries, and museums.
Hitema close control air conditioners have been designed to minimize the space because we
know very well that it is important a minimum foot print and front maintenance space inside
technological rooms, but, at the same time Hitema close control air conditioners have one of the
Market’s most advantage ratios between sensible cooling capacity and base foot print.
Except the replacement of heat-exchange coils, ordinary or extraordinary maintenance can be
executed from the front side of the unit, and that means to have more side space available allowing
the installation of several units close to each other. The access is really easy and quick through the
hinged front doors.

The Grasso ammonia Dryer is a useful supplement for every ammonia refrigeration plant. It eliminates infiltrated water from the refrigerant circuit, even while the plant is in operation! Water has a huge affinity with ammonia and the combination effects the evaporation temperature and finally the efficiency of the plant.
Even low water quantities can influence the evaporation temperature by up to1K, which results in an increased power consumption of around 3%.
In addition to increasing the operating costs, the water causes corrosion, leads to rapid ageing of the oil and quickens the forming of slurry.
For these reasons the infiltrated water results in higher maintenance costs. If the refrigerant circuit is dry and clean these drawbacks can be prevented.

Cold Pump® Cooling Systems are thermostatically controlled, closed-loop air conditioners that use CFC-FREE R22 or HFC-134A refrigerants. Room air is continuously drawn through an external filter, across condenser coils (where it removes the heat drawn from the enclosure) and flows out the top external vent. The sealed enclosure remains clean and cool because internal air is cooled and dehumidified continuously as it is drawn across the evaporator coils.
Applications:
Vortec Cold Pumps are a reliable air conditioning system for electrical control panels and enclosures. These units, which maintain NEMA 12 ratings, are perfect for both new installations as well as retrofitting to cabinets already in place. Top and side mount models are available with cooling capacities ranging from 1800 to 6000 BTUH. Provides effective cooling protection for heat-sensitive electronics in numerous applications.

cooling units
determining the cooling unit using charts
In order to select the unit best suited to your requirement, the values of three parameters are required: maximum ambient temlperature in the area where the switchboard is installed Te (max), the maximum temperature required in the enclosure Ts (max) and the amount of heat to be removed by the unit (Psyst.). Use the selection chart related to the reference temperature Ts which is closest to the required value. Read the Te value on the horizontal axis of the chart and draw a vertical line through this point. The intersections of this straight line and the power curves of the various units give the power that each unit can absorb in these
temperature conditions. Select a cooling unit with a power rating
immediately above the the Psyst. value to be removed.

Lytron's cooling systems can be tailored to your precise requirements with a range of standard options, or completely custom designed for OEM volumes. Its cooling systems are used in a variety of applications including medical and industrial lasers, analytical instruments, oncology machines, electron microscopes, printing equipment, plasma etch systems, and solder reflow ovens.
Lytron offers three types of cooling systems - compressor-based chillers, liquid-to-liquid cooling systems, and ambient cooling systems, detailed below:
Recirculating Chillers (Kodiak)
Cooling capacities up to 6 kW
Kodiak compressor-based recirculating chillers are an ideal solution when you need a cooling system with precise temperature control (±0.1°C) or cooling below ambient temperature. Applications include medical equipment, medical and industrial lasers, electron microscopes, analytical instrumentation, semiconductor processing, and printing equipment.
Liquid-to-Liquid Cooling Systems (LCS)
Cooling capacities up to 20 kW
Liquid-to-Liquid cooling systems offer precise temperature control of process water and transfer the waste heat to facility water. They are ideal for high heat load applications where precise temperature control (±0.5°C) is needed and chilled facility water is available. Applications include medical equipment, industrial machine tools, printing equipment, and cabinet cooling.
Ambient Cooling Systems (Modular Cooling System%u2014MCS)
Cooling capacities up to 3.5 kW
Modular Cooling Systems are non-refrigerated cooling systems. They are a cost-effective alternative to recirculating chillers for applications where precise temperature control and cooling below ambient temperature are not required. Applications include analytical equipment, cabinet cooling, medical equipment, and laser systems.
Every cooling system that Lytron sells is backed by its world-class service operation to provide rapid and affordable service, should the need arise.

Avoid any downtime, with the most affordable, reliable, and easiest to install thermal protection product available for electrical enclosures!
Just as quiet as an air conditioner (about 62 dBA), the Vortex A/C noise level is 73% less than other conventional, vortex type cabinet coolers. When the thermostatically-controlled Vortex A/C is operating, the decibel level is about the same as normal human conversation!
This next generation, Vortex Cooler features an integral mechanical thermostat to conserve energy and maintain enclosure temperatures within a range of 27° to 32 °C. Requiring only a compressed air supply to operate, the UL listed Vortex A/C quickly installs in a 1,5" knockout hole to keep electrical control panels cool, clean and protected.
When the going gets tough...
Using vortex tube technology, cold air is generated by the Vortex A/C from the compressed air supply and is distributed throughout the enclosure. Since ambient air never enters the cabinet, it's perfect for harsh, dirty environments. In fact, the Vortex A/C features an optional "purge-air" port that, when opened, will provide a constant positive pressure inside the enclosure to purge the cabinet of any contaminated surrounding air. Withstanding extreme temperature conditions, the Vortex A/C will provide reliable cooling operation in environments up to 79° C.

The Peltier effect is a thermoelectric effect, named after the French physicist Jean Peltier. Respectively doped (n-type and p-type) semiconductor materials are used, which are alternately connected in series, each at two junctions. An electric current flowing through that system causes a change in the energy level of charge carriers, thus providing heat being absorbed at one junction and being evolved at the other.

HXi™ Series Heat Exchanger
Our HXi™ Series air-to-air heat exchangers are designed primarily for cooling indoor and outdoor electronic enclosures. They use a double-sided impingement technology to significantly improve heat transfer performance while reducing heat exchanger size. Tests verify that the HXi™ heat exchanger is capable of dissipating twice the heat load of competitive heat exchangers at a comparable size.
Thermacore’s patented design makes the HXi™ Series a low-cost and high-performance alternative to conventional heat exchanger technologies. There are fewer moving parts for greater overall reliability. Standard units are available with 2, 4, 6 or 8 fans. Custom optional features such as alarms and temperature controls are also available. Units are UL recognized and meet Bellcore GR-487-CORE, NEMA 4 and NEMA 12 requirements.
