High-temperature commercial air conditioner PT 6500 HT

This mobile split air conditioner performs at its best even at high outside temperatures – can be used up to +55 °C ambient temperature

High-temperature air-conditioning unit PT 6500 HT – for ambient temperatures up to +55 °C

PT 6500 HT – the name says it all:

HT stands for “High Temperature”, as these are exactly the climatic conditions for which the mobile air conditioner PT 6500 HT has been designed.

It is not only in T3 climate zones that extreme outdoor temperatures prevail in the summertime. Even in previously more temperate climate zones, heat waves with very high temperatures are becoming more frequent. Conventional air-conditioners quickly reach their limits because their construction usually only allows them to operate as intended up to a maximum ambient temperature of +38 °C.

PT 6500 HT air conditioner – the mobile solution for high-temperature environments

Whereas the outside of the housing is structurally identical to its sister model PT 6500 S, all internal components of the PT 6500 HT's compressor refrigeration system are designed for use even in extreme summer conditions with temperatures up to +55 °C. In combination with the more powerful PT S+ heat exchanger, all components reliably generate a continuous flow of cooling air in environments with a temperature range of +7 to +55 °C.

The special cooling unit design of the PT 6500 HT ensures that this mobile air conditioner can provide maximum cooling performance even in extreme temperature conditions in T3 climate zones. And Duplex-Cooling even makes it possible to extend the application area to environments up to +60 °C.

Powerful cooling technology for continuous operation in high-temperature environments

Numerous detailed solutions prove the soundness and high quality of this professional air conditioner. For example we used super robust finned aluminium heat exchangers with thick-walled copper tubing. Additionally, the heat exchangers' rotary compressor was fitted on vibration absorbers to ensure the maximum lifetime. In addition, all internal components of the compression refrigeration system are designed for the use in high ambient temperatures up to +55 °C. Thus, a powerful centrifugal fan with radial flow ensures large-volume cold air circulation.

Once installed at the site of operation, the PT 6500 HT is ready for use within only a few minutes. For the power connection you simply require a 230 V outlet, and thanks to the connection set with quick-lock couplings, the connection to the external heat exchanger is established in no time. The connection line just contains circulating water mixed with glycol, so that there is no refrigerant loss when the PT 6500 HT is connected and disconnected. And by combining several connection sets the covered distance may be increased to maximally 30 metres, if required. This permits the cooling of remote, windowless rooms.

Typical applications:

  • Personnel cooling in high-temperature environments such as steelworks, aluminium foundries, copper works
  • Cooling of guest or staff areas in tropical climates
  • Mobile cooling even under T3 climate zone conditions
  • Reliable permanent cooling of computer rooms, measuring and control centres
The mobile air conditioner PT 6500 HT is perfectly suited for a variety of cooling applications in high-temperature environments

Practical details for the quick application into frequently changing environments

All operating settings can be made quickly and easily made via the user-friendly control panel, which also provides a central display of all status indications with regard to the operating mode, blower level or room temperature.

The air conditioner PT 6500 HT was manufactured in an especially slim design, allowing it to fit through any door and into every lift without any problems.
Transport-friendly slim design
A recessed service compartment at the rear houses all device terminals and at the same time serves to store the connecting cable for transport purposes.

Connecting as quick as lightning thanks to water cooling circuit with quick release fastener

PT connection sets with quick-lock coupling

Installing connecting lines flexibly, quickly and easily – this feature is certainly a plus:

The air conditioning systems of the PT series come with two separate cooling circuits. The refrigerant circuit of the basic device is hermetically sealed. By contrast, another circuit is installed between cooling unit and external heat exchanger for cooling the condenser as well as for heat removal using a connection set. In this additional circuit only water with a low glycol concentration circulates as cooling medium, thus ruling out a loss of refrigerant when connecting or disconnecting the devices in a professional fashion.

For a quick installation of the water and power lines between air conditioner and heat exchanger the connection sets of these air conditioning systems come equipped with high-class quick-lock couplings. As a result, even longer connections over a distance of up to 30 metres can be realized without difficulty in a quick, clean and easy manner – ideal for office, server or production rooms, control centres or studios, where there is hardly ever any room to accommodate such heat dissipation measures.

Patented passage underneath doors PlanoPT

Plano PT even opens up installation paths to you the access to which has been denied to you so far

The exclusive Trotec PlanoPT Allows for the installation of the PT connecting lines underneath all common interior and exterior doors. In this way, even rooms without a conventional installation access can be equipped with cooling units by means of the patented PlanoPT. Find out more about the benefits of Trotec's PlanoPT ...

Quick installation using PT connection sets

With the air conditioners of the PT series it is possible to install the external heat exchanger up to 30 m away from the cooled room by using connection sets. The hoses are simply led through ceilings, walls or along the floor.

Optional passage underneath doors with PlanoPT

With the PlanoPT connection feedthrough, which is available as accessory, connection sets can be installed and connected underneath doors. The connection sets of the PT models are optionally also available in a length of 5 m and can be flexibly combined with the 10 m lines to an overall length of 30 m.

Functional diagram PT 6500 HT

Split design – bundled cooling power

The interior unit of the PT 6500 HT houses a powerful cooling compressor system with a hermetic refrigerant circuit. Within this circuit, the sucked-in room air is cooled down to the setpoint temperature selected and then emitted as cooling air to the room again via the pressure-resistant radial fan. The air recirculation of the PT 6500 HT provides the additional benefit that neither interior air is consumed nor underpressure is generated.

As a result of the process, refrigeration also produces heat. In order to prevent this heat from also entering in the room air again, the process heat generated in the condenser is dissipated in a separate system via a circulating cooling medium to the external heat exchanger by means of a pump.

The connection between the interior unit and the externally placed heat exchanger can be quickly established using the PT connection sets. They are provided with quick-lock couplings and allow for an overall installation path of up to 30 metres between the interior and external unit.

The cooling medium circulating in the connecting lines is only water with a low glycol fraction, thus preventing the loss of refrigerant when the devices are professionally mounted and dismounted.

In the external unit the cooling medium then flows through a large-volume heat exchanger, through which sucked-in ambient air is blown for the purpose of thermal absorption. In a last step, the cooling medium with its now reduced temperature flows back to the interior unit via the connecting line to absorb new heat there.

Invaluable practical benefits for rental companies

A high degree of versatility by Duplex cooling with DualHex coupling – ideal for extreme ambient temperatures of up to +60 °C.

Benefit from an extended operational range of the air conditioner PT 6500 HT via Duplex Cooling by connecting two heat exchangers of type PT S+ in series to the connecting line via DualHex coupling now instead of one heat exchanger.

DualHex coupling for the Duplex cooling application

For the air conditioner PT 6500 HT, Duplex Cooling enables a ΔT increase of the upper working range limit value by 5 °C.

With this technology, the air conditioner PT 6500 HT can even be used with ambient temperatures of up to +60 °C – or the device does not run under full load at lower temperatures.

For optional Duplex cooling operation, in addition to the DualHex coupling, an additional heat exchanger of the type PT S+ is required.
