c.Compressor: world famous brand semi-closed screw-type or fully closed scroll-type compressors;

d.Running advantage: Low energy consumption, stable operation, little vibration, low noise.

e.Components: Using high quality imported components, system with optimal design, stable operation of unit;

f.Refrigerants: Environment Protection refrigerants like R134a, R407C, R410A and other as request; No combustion, no smoke, no boiler or cooling tower makes the environment more beautiful.

g.Low running charge: The running charge only 1/3 to 1/2 of the traditional air conditioner;

h.Application: hotels, restaurants, hospitals, office buildings, theaters, stadiums, residential quarters, textile, food, medicine, metallurgy, chemicals and boiler works etc.

Design Features

     With affordable design concepts,clients will enjoy high-quality with best price.

Optimal Performance & Energy-efficient

* Direct drive semi-enclosed twin-screw/soft scroll compressor is specially developed for heat pump system, with high quality and reliable performance, high energy efficiency and long lifetime.

* Advanced design of thrust balance drum combination increases 3-4 times lifetime of the bearing.

* Multistage energy regulate ensures efficient operation in part load mode.

* Capacity control no-load starting effectively reduces the impact on electric power network.

* Good maintainability

Simple Structure & Stable Running

* Each unit is an option design of the combine of single compressor and double compressors, with the least motion parts to bring you the highest stability

* Stable running, low noise and little vibration, low requirement to the engine house, high flexibility of application

* Less vulnerable parts, making the cost of operation and maintenance greatly be reduced

* Built-in multistage oil separator, with high separation efficiency

Stable Control & Simple Operation

* Industrial grade microcomputer controller improves anti-interference capability of the control system and ensures sustained and stable operation of units

* The large backlit LCD monitor with blue dot can display 10 lines with 16 Chinese characters a line. Relational information of operation and faults is clear.

* Touch-key and menu-prompted make operation simple and clear.

* Remote DDC control switches plants.

* Reserved RS232 and RS485 communication interface and integrated open MODBUS protocol can conveniently implement the connection between upper part computers and building management and control systems.

* Various parameter setting and password protection prevent incorrect operation.

* Timing switch plants control and real no manual guard.

* A variety of protection functions ensure safe and stable operation of units

Compact structure & Easy installation

* Integral unit design, compactness and precision, small floor space.

* Save engine house space.

* Simple and beautiful arrangement of the external piping reduces the risk of damage.

* Before the unit leaves the factory, the refrigerant has been injected. What you need to do is to connect the water pipes and power, then start up, debug, and operate easily.

*Narrow unit shape makes it easy through a standard doorframe, particularly for renovation project.

Reliable Safety & Low Failure Rate

Control center provides a variety of functions protection to ensure safety and stable operation of the unit:

* High pressure, low pressure, oil temperature, phase sequence, phase loss, overvoltage, undervoltage, phase imbalance, overload, and ultra-temperature multiple protection. Flooded evaporator:

* Nozzle oil return, which structure is simple and reliable.

* Completely vaporized refrigerant. There is no danger of slugging. The design with single Compressor and single loop and the design with double compressor and single or double loop:

* Least parts.

* Best reliability.

Simple and Practical & Low-cost   

High pressure compressor:

*Long lifetime, low operation cost, compact structure, and full equipments.

*Installation is convenient, which reduces the cost of installation largely. Its control is also simple.

*Little Human input and saving maintenance costs.

Dry/wet evaporator:

*Small amount of refrigerant injected.

The design with single compressor and single loop:

*Low maintenance costs and less vulnerable parts

Quality Assurance & International Standard

*Producing enterprise of high quality: LVTE Corporation.

*Service teams of high quality: Professional maintenance staff from LVTE Corporation.
