Key Applications
Solution Overview

Digital and useful tools for HVAC/R
With the continuous development of HVAC/R technology, the running and maintenance requirements on refrigeration and heating systems are also increasing. Thus, we provide smarter and more practical tools for staffs to improve work efficiency and simplify operation processes, ensuring that systems are more efficient and reliable. See followings for a brief introduction on refrigeration and heating systems’ applications.

Refrigerant Leakage
When the refrigerating efficiency is reduced or the energy consumption is increased in the refrigeration system , it may be the refrigerant leakage in the system. If it is not maintained and repaired in time, it will lead to the compressor damage in the long term, causing the system failed or running life shortened.
The UT336A/UT336B can be used to detect the refrigerant leakage, slowly move the probe along the pipeline, the device alarms when detects the leakage, and the sensitivity of probe can be adjusted for efficient detections of different concentrations. Accurately locate the refrigerant leakage can provide a better maintenance.

Refrigerant System Installation & Debugging
When installing or debugging the refrigeration system, read and record the pressure and temperature at high- and low-pressure.
UT336E Digital Manifold Gauge and UT336P Wireless Pressure Gauge support various refrigerant types, display the real-time changes of pressure and temperature , and function data storage, Bluetooth connecting APP and data exporting.
By using UT336E, maintenance personnel can determine whether there is leakage, blockage or other failures in the system, quickly locate the leakage, and adjust the system in time.

System Vacuuming
The purpose of system vacuuming is to remove air and moisture from the refrigeration system, ensuring the efficient running and long-term reliability of system.
During the installation or maintenance of refrigeration systems, connect the vacuum pump to UT336E Digital Manifold Gauge, enable the vacuum pump and discharge the refrigerant from the system to create an empty state.
In the process of vacuuming, use UT336V Vacuum Gauge to monitor the vacuum degree and ensure the running state of system.

Refrigerant Injection
When the system reaches the desired vacuum, connect the refrigerant bottle.
Use an Electronic Refrigerant Scale to accurately weigh and slowly fill it into the system.
Check the running pressure and temperature of system to ensure that it is within the normal range.

The common features of these products:
♦️ iENV, More Powerful, More Compatible
Say goodbye to the tedious, welcome the intelligent! iENV can not only connect various environmental meters, but also connect with refrigeration measurement tools through Bluetooth, monitor the real-time data, generate and export accurate reports, and analyze data conveniently. Whether it is to set the parameters of device or in daily operation, an APP can do it, making work more efficient and easier.

♦️ Measurement of Multiple Refrigerants
Support to measure multiple refrigerant types (When a new refrigerant type is added, it can be updated through the app.)
♦️ Measurement of Multiple Targets
Use advanced tools to measure the temperature, pressure, leakage and vacuum of refrigeration system. Make sure the system runs efficiently!
♦️ Visual Alarm
With LED indicators, get to know the alarm state clearly.
♦️ IP Rating
Durable and Reliable
♦️ Easy-to-Carry, Portable
For example, UT336E provides a practical tool box.
