Production
Starting from the specifications and / or directives of the client, we can create any type of design to implementation / prototyping,
manufacturing series, offering a full service integrated design according to
international regulations and standards of fact.
Furthermore ENTESC has standardized the following systems to military specifications which are included in its product catalogue:
- CHL and CHP CHILLER to cool water and glycol mixtures, for field and naval applications
- HVI and HVL air conditioning systems for indoor shelters
- HVE air conditioning systems for outdoor shelters
- NBC outdoor units
CHL – Military Chiller
The units of the CHL family are designed and built to be installed outdoors, in naval and field environments and on trailers.
The main features are:
Fully shielded outer casing with EMI/environmental gaskets and honeycomb filters on the condenser air inlet to withstand the EME environment described in MIL-STD464A.
Designed to meet MIL-STD461F EMC and MIL-STD810G environmental requirements. Ethernet connection to interface with a remote supervisory system. Equipped with quick couplings and connectors for rapid deployment. Low noise Remote diagnostics Operating temperature: -20°C / +50°C Storage temperature: -40°C / +71°C
Activities carried out recently are listed below:
- Oil&Gas: HVAC for OIL & Gas application, ATEX / IECEX certified, with cooling power in the range 7KW to 140kW:
- Under the frame of a militar program for an important national client and international main contractor, ENTESC has designed and supplied the air conditioning systems (P/N 128-00-000) for shelter with high innovative performances:
- Cooling capacity 6kW @50°C
- Nominal working temperature: -35°C / +55°C ; STANAG 2895 (Nato AECTP 230) Category :
A1 Extreme Hot Dry , A2 Hot Dry, A3 Intermediate , B1 Wet Warm, B2 Wet Hot , B3 Humid Hot Coastal Desert , C0 Mild Cold ,C1 Intermediate Cold
- Power supply 220V 1ph, but with low inrush current by means of a device able to reduce compressor startup current.
- Noise reduction by means of variable fan speed (lowest noise level is 53dB)
- Drying function
- The unit is designed to be mounted on a front panel (optional) on which are present EMI/environmental gasket and Honeyconmb filter, these allow an high level of protection against external EMI disturbance. This fron panel is realized so that the air contitioner can be easily installed and dismounted externally from the shelter by means of fork lift.
- The mechanical structure of the air conditioning was then verified by analysis in accordance with the requirements of mechanical vibration described in
MIL-STD 810E Procedures - The Method 514.4 and the mechanical requirements of aviation transportation on C130J
- Low size and reducted weight

Under the frame of a militar program for an important national client and international main contractor, with the end customer the Italian army, ENTESC has designed and supplied the free-cooling air conditioning systems
(P/N 102-00-000) and
ventilation systems (P/N 114-00-000) and lighting explosion proof (ATEX).
The unit has been developed to be installed inside a UEO2 shelter. ENTESC was able to design from scratch, develop, implement, test, qualify and deliver these items in less than 4 months of starting work. The HVAC unit has been designed to work in outdoor temperature operating range of -46 ° C / +55 ° C, especially in climates described in
STANAG 2895 (NATO AECTP 230) Extreme Hot Dry Climatic category A1, A2 Hot Dry , Intermediate A3, B1 Warm Wet, Wet Hot B2, B3 Humid Hot Coastal Desert, Mild Cold C0, C1 Intermediate Cold. Cold C2. The mechanical structure of the air conditioning was then verified by analysis in accordance with the requirements of mechanical vibration described in
MIL-STD 810E Procedures - The Method 514.4 and the mechanical requirements of aviation
transportation on C130J. The free cooling operation mode
provide a high level of reliability to the system. In free cooling mode the system continues to operate even in case of critical failures within the unit,
allowing the system to work in degraded mode.

Design and development of a dual redundant air-conditioning system (P/N 115-00-000). The system was designed and built to be installed in
20''shelters for the Italian Army. The system is composed of two
ACU units , having a cooling capacity of 10kW@50°C each, and from a
remote control panel. The two units are controlled by the remote control panel RCCP. On the front of RCCP failures and indications
are shown. Inside RCCP is present an electronic thermostat, allowing the adjustment of the temperature inside the compartment operators.
