上排風(fēng)機(jī)組 Upper Exhaust Fan Unit

         ??

• 國際領(lǐng)先的制冷壓縮技術(shù)。性能可靠，結(jié)構(gòu)緊湊，能效比高。

• 采用高效蝶形閥片，吸排氣氣流通暢，大大減少吸排氣阻力。

• 油泵強(qiáng)制供油及獨(dú)特油壓差控制裝置。

• 特有的噴液冷卻設(shè)計(jì)更適應(yīng)低溫工況下可靠運(yùn)行。

• 獨(dú)特內(nèi)置溫度保護(hù)裝置，對電機(jī)及壓縮機(jī)的過熱運(yùn)轉(zhuǎn)提供了有效保護(hù)。

• 帶有曲軸箱PTC加熱器，確保長時(shí)間停機(jī)或環(huán)溫過低時(shí)壓縮機(jī)安全啟動。

• International leading refrigeration and compression technology. It has reliable performance, compact structure and high energy efficiency ratio.

• The butterfly valve with high efficiency is adopted to smooth the suction and exhaust airflow and greatly reduce the suction and exhaust resistance.

• Compulsory oil supply of oil pump and unique oil pressure difference control device.

• The unique spray cooling design is more suitable for reliable operation at low temperature.

• Unique built-in temperature protection device provides effective protection for overheating operation of motor and compressor.

• PTC heater with crankcase ensures safe start of compressor when long shutdown or ring temperature is too low.
