cooled
Services hub installation needs:
¾” demineralized water supply
50mm water drain at floor level
Electrical cabinet installation needs:
Supply power (-40°C~+150°C):
400VAC, 50Hz, 80A / 3-Phase + Neutral + Ground
Electrical protection: Circuit breaker 3 x 80A + N with 300mA
differential
3-Phase electrical cable
Water cooled:
-Water flow (at 25 ºC):
- up to 5000 litres/hour (for 40 ºC models)
-Intake pressure: 2 to 5 bar
-Water entry and exit pipe: 1” or 28mm
-Differential pressure between entry and exit: ≥ 2,5 bars
-Maximum temperature of water entry: 26 ºC
-Minimum temperature of water entry: 16 ºC
R-ecommended temperature of water entry: 18 ºC
TEMPERATURE SENSORS
• One (1) PT 100 Class A, located in air treatment tunnel
• One (1) PT 100 Class A, movable sensors for flexible placing
inside chamber
HEATING
• By stainless steel electric heaters located in the air treatment
tunnel
COOLING
• Mechanical compressor group Scroll (low noise, high efficiency)
with enforced ventilation and without use of CFC’s. In -60ºC models
water cooled condenser
is used as standard. As an option the system can be cooled by an
air condenser.
THERMAL SECURITY
-Safety thermostats with High / Low temperature configuration, with
automaticstop of all heating systems.
-High / Low temperature alarms programmed in the controller, with
mute function.
-This function won’t stop the chamber and it’s only used to record
the occurrence and to call the attention of the users with an
audible alarm.
HUMIDITY SENSORS
• To measure and control humidity,Jianqiao has different sensor
technologies: Psychometric, Capacitive, or both.
Consult us for technical support on the
appropriate selection.
HUMIDITY / DRYING
• Humidity: Through thermostatic bath with dew point control.
• Drying: Through thermostatic bath with dew point control and
additional dry coil
SECURITY
• Automatic stop function in case of water failure, with indication
on the controller;
High / Low Temperature alarms; Compressor overload and overheating
alarm .
CONSTRUCTION
• Interior: AISI 304 hermetical welded, vapor tight, stainless
steel
• Exterior: SECC steel with epoxy coating finish
• Insulation: Rock Wool
• Interior illumination: Halogen lamp 12V (only available with
optional window)
• Door: Double silicone joints and anti-condensation heating
frames.
