ISO 9001:2015 hi chiller-te tan bik a ni lo nain, a tlangpuiin siamtute chuan he quality management system certification hi control theih production process leh product consistency an neih theih nan an dawng tur a ni.

3. Key performance indicator te .

Domestic emaw international standards zawm emaw pawh nise, closed-circuit evaporative coolers te tana performance standards te hian a hnuaia performance indicator te hi an ngaih pawimawh ber a ni:

Thermal performance: Cooling capacity (KW), inlet leh outlet water temperature danglamna (ΔT), leh heat transfer efficiency (%) te pawh a tel.

Tui hman leh energy hman tangkai dan: Tui hman dan (circulating water utilization rate), fan leh pump energy hman dan ratio (KW/REFRIGERATION TON).

Thil hmanrua leh a chhe thei laka invenna: Shell material (eg, fiberglass, stainless steel), heat exchange tubes (eg, copper, titanium) te corrosion resistance.

Hriselna leh boruak humhalhna: Electrical insulation level, noise limit (DB), leh anti-freeze design (a hniam-temperature regions tan) te.

4. Standards pawimawhzia .
