Commercial air conditioner PT 23000 S
The most powerful mobile split air conditioner with refrigerant-free connecting lines on the market
Mobile cooling for professionals
The flexible mobile air conditioner PT 23000 S was designed specifically for the demanding requirements in rental business and is characterized by an equally robust and transport-friendly split design, extreme maintenance-friendliness and reliability in cooling operation. Thanks to the quick-lock couplings at the connection set the external heat exchangers can be connected in no time. Install, connect the heat exchangers, connect the power supply, ready for use – quickly in only a few minutes!
The connecting line just contains circulating water mixed with glycol, so that there is no refrigerant loss when the air conditioner is connected and disconnected. By combining several connection sets the covered distance may be increased to maximally 30 metres, if required, which therefore also allows for the cooling of remote rooms.
The design is implemented along the lines of the function – consistent to the last detail
The robust design of the PT 23000 S with hardwearing panels made of galvanized and additionally powder-coated steel ensures a high resistance to climatic influences and aggressive surroundings.
Equipped with sturdy castors and designed in an especially slim fashion, this air conditioner can be easily transported and manoeuvred in the smallest space – the PT 23000 S fits through every door and into every lift. Due to its specially reinforced housing, the cooling unit with its optional crane lugs can also be easily transported by means of a crane. Two integrated bar handles additionally protect the front panel from impact damage while simultaneously allowing easier handling.
Powerful cooling technology for continuous operation
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.
Together with the adjustable outlet grille, two powerful radial fans for large-volume air circulation ensure homogeneous cooling even of large rooms. Due to microprocessor-controlled hot gas defrost cycles as well as the preselectable blower level and target temperature, the optimum room temperature for every cooling requirement can be achieved – depending on the operating conditions even to below 10 °C.
Its robust and compact design and the high performance of the PT 23000 S make this air conditioner the first choice for numerous cooling applications – and, with its optionally available top piece, also as a spot cooler.
Practical details for the quick application into frequently changing environments
Connecting as quick as lightning thanks to water cooling circuit with quick release fastener
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.
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 ...

Split design – bundled cooling power
The interior unit of the PT 23000 S 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 two radial fans which produce powerful air recirculation. The air recirculation of the PT 23000 S 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 exchangers by means of a pump.
The connection between the interior unit and the externally placed heat exchangers 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.
Spot cooling option
For the cooling of system parts, often not the steady reduction of the room temperature as a whole is relevant, but the targeted cooling down of special components, for instance, generating a large amount of heat.
Typical applications are for example computer centres or SMT machines the sufficient cooling of which can no longer be reliably ensured in existing installations during the hot months.
For such applications, the PT 23000 S can also be utilized as a spot cooler if required. By means of the optionally available spot cooling attachment, the cooling airflow generated can be focused and directed accurately at the spot to be cooled via the air transport hose connected.
What cooling capacity do your rooms require?
For business facilities, surgeries, offices or warehouses, you can use the following values to carry out a quick and approximate determination of your demand for the cooling capacity required:
- 30 watts per cubic metre
for ideal-typical business facilities along the lines of passive house standard, normal sized window area and little frequented
- Additional 10 watts per cubic metre
in case of poor insulation
- Additional 10 watts per cubic metre
if there are more than 3 individuals in the room
- Additional 10 watts per cubic metre
if the size of the window area exceeds the average
- Additional 10 watts per cubic metre
if the windows and/or outer walls are facing south
- 50 watts per cubic metre
for attic rooms.
Especially in case of attic rooms in old buildings determining the required cooling capacity remains a difficult task due to the lack of knowledge regarding the roof's thermal insulation. Just to be on the safe side, take 60 watts per cubic metre as a basis, in the case of poorly insulated roofs and many skylights, still more.
- 55 watts per cubic metre
when using air conditioners in construction site trailers

Invaluable practical benefits for rental companies
A high degree of versatility by Duplex cooling with DualHex coupling – ideal for extreme ambient temperatures
Benefit from an extended operational range of the air conditioner PT 23000 S via Duplex Cooling by connecting two heat exchangers in series to each of the three connecting lines via DualHex coupling now instead of one heat exchanger.
In this way you can operate the air conditioner PT 23000 S with a total of six heat exchangers of the type PT S+ – two heat exchangers on each of the three connecting lines in each case.
Duplex Cooling allows for a ΔT increase of the upper working range limit value by 7 °C.
With this technology, the air conditioner PT 23000 S can even be used with ambient temperatures of up to 42 °C – or the device does not run under full load at lower temperatures.
For optional Duplex cooling operation, in addition to three DualHex couplings, three additional heat exchangers of the type PT S+ are required.
