Emerson and WOTECH achieve strategic cooperation

Emerson and WOTECH achieve strategic cooperation

On the 16th, January,2014s,with the invitation of American Emerson OhioS tate headquarters. WOTECH sales manager-Stella Yau, a president of WOTECH, leading our export department inspiring our green, safety, energy saving products. For business exploration, Stella visits American Emerson company and strengthen strategic cooperation with each other. Emerson company think highly of strategic cooperation with WOTECH, a heart stirring news is that “2014s Copeland compressor ZW apply in heat pump water heater and extending strategic cooperative partner certification was issued by Emerson company”. In other words, an important significant strategic cooperation will be achieved between WOTECH and Emerson company.

Emerson Via president issued certification of 2014S Copeland compressor strategic cooperative partner.

American Emerson environment technology company specialize in air-conditioner compressor for years, which is world famous leading manufacturing company. Higher efficiency than any other non-professional compressor company. It is known to us all that, heat pump compressor are use all year round. And this means that compressor needs to be worked in severe environment and promising fan motor coil bear high temperature working conditions. The normal compressor will not do that.

WOTECH is a professional heat pump manufacturer in China. with 260 workers, three branch office in China, combine with design, manufacture, production, supervise and quality control. 12 years experiences, CE/CB+ISO+ETL certificated, this is reason that we keep good quality and competitive prices for global valued customers.

Also, Copeland compressor are used in our commercial heat pumps, which higher efficiency than other heat pumps. Thus, we make sure that WOTECH can lead heat pumps field go forwarding in the future world.

Air source heat pumps

Air source heat pumps

Air source heat pumps are positioned outside, adjacent to the building, and have a fan that draws in outdoor air over a large heat exchanger which harnesses the heat energy in the air, even at temperatures below zero degrees, and transfers it to the refrigerant, triggering the refrigeration cycle. Air source heat pumps usually consist of the external unit and an internal unit where hot water is stored and the controller and circulation pumps are housed.

All kinds of heat pumps can be choice.

Domestic hot water heat pump

For house heating and sanitary hot water, which is extremely suitable for floor heating system.

Swimming pool heat pump

For swimming pool heating and fish farming, which is adaptable for all types of terminals and ideal replacement for water heater. It can be used to heat, cool, or keep water temperature constant for pool or spa.

Different cabinet, different COP series are available for various locations.

Commercial heat pump

Commercial heat pump such as ultra-low temperature heat pump, it can use to heating in the severe cold area, hot water reaches 80 degree.

How to Conduct Titanium Heat Exchanger Leakage Check?

Refrigerant Water Leakage Check

Connect the heat exchanger with water pipes and charge water pressure up to 4 bar to see if water leaks from the PVC shell. 100% check on every heat exchanger with 4 bar water pressure and 6 bar as random check on some pieces.
P.S.: Water pressure for normal pool system is 2 bar only.

A round green QC passed sticker will be put on the heat exchanger to show this is QC passed.

A green square sticker will be put on the heat exchanger to show this passed 6 bar randome check.

Flow switches been checked before they are installed on the heat exchangers so green stickers are also on each flow switch here.

Refrigerant Circuit Leakage Check

Tianium heat exchangers are kept at high pressure of nitrogen in the titanium coil inside for 48 hours to check refrigerant circuit leakage before being assemble, 100% checked.

After 48 hours workers will unscrew the gas valve to check if any gas pressure inside the titanium coil to find the leaks. 100% checked. Those fail will be rejected to suppliers.

For more about us please visit www.wotech.cn.

How to Conduct Evaporator Leakage Check?

How to Conduct Evaporator Leakage Check?

* Weld the evaporator with the refrigerant distributing copper pipes (one side blocked).

* Charge 30 bar gas pressure (nitrogen) into the evaporator and drop it into the water to find leaks. 100% checked.

Now we have developed the high nano meter evaporator fins which absorb heat more effectively. Its design makes form condensed water channels easily. Dirt seldom gather on it.

What Is the Advantage of WOTECH Heat Exchangers?

What Is the Advantage of WOTECH Heat Exchangers?

Wotech produces titanium heat exchangers by its sub-company.

Features:

* Super anti-corrosion ability. Heat exchanger is made of pure titanium and PVC.

* Sufficient volume for flow circulating. With the unique design, liquid moves smoothly inside the short but wide channel. Obstruction is reduced.

* Reaching international standard. Environmentally-friendly PVC shell follows ROSH standard. Besides, it is UL, CE approved.

WHAT IS THE COOPERATION MODE OF WOTECH HEAT PUMP?

Recently, WOTECH proposed the cooperation mode of ACOF (Area Canter of Factory). That is a strategic plan for development. Within a year, distributor “net” will be build with products as the core. In the following half a year, distributors will grow up into a supplier combining internet promotion, logistic and service into one comprehensive uniform. Within 2 years, distributors will turn into qualified air source heat pump providers of energy management with financing ability. Within three years, distributors will master the skill to product integration and installation, with financial ability jumping to a higher level.

Faced with the fierce competition in air source industry, Wotech seeks for steady development. How to stand out in this market? The hardware as quality and techniques must be strong. Besides, management, sales, service should cater to market trend.

WOTECH EVI Heat Pump

WOTECH EVI Heat Pump

EVI is short for Enhanced Vapor Injection, which enables heat pumps to work under minus 10 to minus 25.

Enhanced Vapor Injection system is made up of EVI compressor, EVI technology and high-efficiency condenser. The combination of them provides high performance.

The compressor adopts double-level throttling and mid air-injection technology, along with the flash evaporator to realize vapor injection effect. Under medium and low pressure, the compressor pressurizes the refrigerant and synchronously vaporizing it. Under high pressure, the compressor works normally. In low temperature, the heating efficiency is largely raised. The EVI technology is widely used for scroll and rotary type compressor.

Hot water can reach as high as 60 C. No need for additional heating equipment. It is suitable for ultra-cold areas.
