The chamber body can be installed close to a wall to prevent negative effects on surrounding mea- surement equipment. (Space saving effect) Numerous additional functions developed from extensive field experience. ■ Air-cooled condenser dust filter (Air-cooled refrigerator only) Installed on the back of the chamber, it can be easily replaced and cleaned. Since there is no need to remove body panels, etc., it can be installed in any location, even in a small space. ■ Ambient temperature exposure functions as standard equipment All models are equipped with a damper mechanism for ambient temperature as standard. Compatible with 3-zone standard tests such as MIL-STD-202G stan - dard. ■ Download function of operation history The temperature of test area is automatically saved not only during operation, but also when the chamber is stopped, such as when a problem occurs or after a power failure, so the stresses that the specimen has been subjected to can be recorded without missing. Operation data can be checked on the monitor or downloaded in CSV format using a USB memory device. ● Air flow during cold chamber drying ■ Cold chamber drying function Simultaneously ventilates the atmosphere of the hot chamber, test area, and cold chamber under pre-test conditions, and discharges the remaining moisture in each chamber outside the equipment. Ventilation of the cold chamber, in particular, has the effect of re- ducing the amount of moisture at the start of the test and extend - ing the time until the initial defrosting. (�) The dry atmosphere of the hot chamber is mixed with the ambient temperature atmosphere and discharged. (�) The atmosphere in the test area is mixed with the outside air and discharged. (�) The moist atmosphere of the cold chamber is mixed with the ambient temperature atmosphere and discharged. Hot chamber Test area Cold chamber High temperature Low temperature Moisture Outside Air Exhaust 6 ■ Downwind sensor (optional) In addition to the conventional upwind sensor, a downwind sensor can be equipped. By selecting the downwind sensor, a wide range of testing conditions can be handled.

Please understand the characteristics of each and select the specification that suits your installation location and other conditions. ■ Cooling water installation for water-cooled types (installed by customer) For models that require primary side cooling water installation (NT1051W, NT1251W, NT2051W), please refer to the following for cooling water installation work. We recommend installing a water tempera- ture gauge, pressure gauge, and flow meter to prevent problems from occurring. P WINTECH Outdoor Indoor Cooling tower Circulation pump Pressure gauge Flow meter Water temperature gauge Bypass valve Strainer Valve Required cooling water amount for cooling tower ・4.2 cooling ton ： NT1051W ・6.3 cooling ton ： NT1251W NT2051W Primary cooling water/heat exhaust equipment ■ Precautions when connecting a heat exhaust duct to an air-cooled type Air-cooled types (NT551A, NT1051A, NT1251A) require additional air conditioning at the installation location or outdoor heat exhaust equipment construction depending on the amount of exhaust heat (see specification table). ○A cooling water system that can keep the water temperature below 32°C and ensure a constant flow rate (see below) is required. If the cooling water system stops, the chamber will also stop, so daily inspections of the cooling water system are required to ensure stable operation of the chamber. ○ The heat emitted from the test chamber does not affect the surrounding environment. ○ By managing the cooling water properly, performance will be stable throughout the year. ○ To prevent problems from occurring, we recommend installing a water temperature gauge, water pressure gauge, and flow meter. ○ It is necessary to regularly clean the cooling water piping to prevent scale from adhering to the inside of the cooling water piping and condenser. ○ Heat exhaust equipment for the tester is required. Sufficient ventilation equipment and cooling system are required for heat exhaust. If the chamber is operated in a small room with insufficient air conditioning, the ambient temperature may rise due to the heat exhausted from the chamber, and the chamber may be forced to stop in order to protect itself. We recommend that the installation environment temperature be 30°C or less. ○ Pe r f o r ma n ce v a r ie s g r eat l y d e p e n ding o n t h e a mb ie nt temperature. ○ Maintenance and inspection, such as regular cleaning of the capacitor filter, can be performed relatively easily. ○ The noise is slightly louder than the water-cooled types. ○ Easy to move. Water-cooled types Air-cooled types ＜ Reference ＞ ○ To prevent piping erosion, keep the flow velocity in the piping to 3 m/sec or less. ○ The cooling tower fan must be thermo-controlled. ○ If use in an area where there is a risk of freezing, install a cooling tower heater. ○ Please clean the inside of the pipes regularly (at least once or twice a year). ○ Please refer to the water quality standards for cooling water and make-up water as stipulated in the Japan Refrigeration and Air Conditioning Industrial Standard JR A- GL-02-1994. The above is for reference only, so please consult a specialist when making a selection. ※It is also possible to use a chiller unit.
