Product feature:
1. Refrigeration compressor: Germany / Taiwan Hanbell Bitzer semi hermetic screw refrigeration compressor, high efficiency, low noise, low wear and long service life etc.
2. Heat exchange: Air-cooled condenser for the hydrophilic foil copper tube fin so the heat exchange area and fin spacing appropriate adjustment according to the geographical environment high efficiency.Shell and tube evaporator inlet is specially designed to prevent the refrigerant inside each heat exchange tube of flow distribution more uniform, compact exchanger structure ,end plate removable, convenient for clean maintenance.
3.inner rotor fan: All aluminum shell motor, low speed , big horsepower . fan blade with elevation angle blade structure ,big air volume, static pressure is high, low noise , long service life. 
4. Refrigeration valve: the United States, Japan, Italy Emerson Saginomiya Castel, Danfoss and other brand-name accessories, some units with double valve control design of thermal expansion,ensure the load and the energy efficiency ratio of the system for operating more wide, cold quantity control precision is higher, the unit is always working in a reliable and efficient state.
5. Electrical parts: unit for electrical components are used for international brands, in English / double display man-machine interface touch screen balanced controller, intuitive operation of the unit operation is more simple, multi compressor system, automatic control system according to the operating conditions of the compressor running time, stable performance
6. Energy regulation: the unit has multi-level energy regulation, to meet the needs of cold load changes, the maximum energy saving effect, saving maintenance costs and operating costs.

Safety protection:
1. exhaust valve: ensure the compressor runs- after stop, to prevent high pressure exhaust gas reflux..
2. Phase protection: to prevent excessive voltage, less voltage, lack of phase protection, reverse phase protection, to prevent the compressor reverse and damage..
3. oil heating protection: before refrigerator runs, forced to set the oil heating procedures to ensure that the oil dilution and liquidity, satisfy the lubrication conditions before operation.
4. compressor internal motor winding thermal protection: to prevent the compressor excessive load or bad condition put the coil temperature too high and burned the compressor.
5. high and low pressure protection: when conditions are bad and failure, high and low pressure switch action protection, protection compressor and system safety..
6. safety valve: ensure the condenser  working in the safe range.
7. water protection: to prevent the unit running without water.
8. anti icing protection: when the unit running, prevent the water temperature too low, the formation of internal evaporator icing and damage the evaporator.
9. overload protection: double protection of soft and hard to ensure compressor overload safety.
10. compressor oil pressure protection: the unit is running, due to poor oil system, leading to insufficient oil pressure, timely protection of compressor.
11. Oil level protection: compressor protects the compressor when the system less oil.
The unit is widely used in: aluminum oxide, aluminum oxide, electroplating, hard plastic, injection molding, extrusion, foaming machine, hydraulic equipment, laminating machine, bottle blowing machine leather embossing machine, composite flooring, food, chemical, biological, pharmaceutical, electronics and other industries
 
 

 

Portable Recycled Hammock

There are currently a wide variety of hammocks available. There are hammocks that are designed specifically for
backpacking and include mosquito netting along with pockets for nighttime storage. There are hammocks made
out of thin and lightweight material which makes them ideal for taking on day trips. Other hammocks include
self-standing metal or wood structures that support the hammock. Given that hammocks are commonly similar
lengths to accommodate for an average adult's height, most hammock stands are universal in design, typically
featuring a spreader bar that runs along the ground, feet for stability at each end, and a diagonal arm at each
end to provide two hanging points. Although they are usually bought premade, it is also possible to make your
own hammock.

For non-spreader-bar styles, the way in which they are hung is critical for comfort. Generally, a higher attachment
point is preferred as well as a sufficient length between points, though these two dimensions can be adjusted to
compensate for a lack in one or the other. The optimal angle of the attaching lines to the post/wall/tree is usually
about 30 degrees. Hammocks can be attached to the anchor points using a variety of suspension systems,
including ropes and webbing straps.
