KOBELCO Screw Refrigeration Compressors Always Leading the Times

As a pioneer of screw refrigeration compressors, KOBELCO has taken the lead in the industrial all along, responding to customer's needs always with innovative ideas and proposals.As the new generational of conventional fixed speed drive model SH series, KOBELCO has developed iZ series in 2002, the world first Integral Two Stage Inverter Drive Freon Screw Compressor condensing units with higher cooling capacity than ever before.This series was followed in 2003 by iZα series of an epoch making non-ozone-depleting compressor condensing unit models using refrigerant R404A.iZαⅡ series is iZα series second generation equipped with "New iZ monitor"

With maximized freezing capacity combined with outstanding energy-saving performance in an unheard-of way, iZα series compressor condensing units are being highly acclaimed by customers.KOBELCO's unique theory and technology (patent acquired) that backed iZ and iZα series have received high praise in various industrial circles, being granted the Technology Award from the Japan Society of Refrigeration and Air Conditioning Engineers and the Japan Machinery Federation's Best Energy-saving Equipment Award.

We pursue untiring efforts towards development of earth-friendly products and continue being all attentions to our customer's voice so that we can offer such safe products that can be used with peace of mind while meeting the diversified needs of customers.

Refrigerant R404A does not deplete the OZONE layer.

Since the production of specified ozone-depleting HCFC-based refrigerants (R22) began to be sharply reduced in 2004 and will be completely banned in 2020, a prompt shift to non-ozone-depleting HFC refrigerants is required for compressor condensing units.With zero ozone depleting potential, R404A is a new, environment-friendly HFC refrigerant.

The new HFC refrigerant 404A is similar to the conventional HCFC refrigerant 22 in pressure property and easy to use.

	Refrigerant compositio	ODP	Saturation pressure	Toxicity	Safety
New HFC R404A	Blended refrigerant (Pseudo-azeotropic mixture) （HFC125: 143a: 134a=44: 52: 4 wt%）	zero	2.3MPa	Non-toxic	○
Conventional HCFC R22	Non-blended refrigerant （100 wt%）	0.055	1.9MPa	Non-toxic	○

* The above saturation pressure values are measured at standard condensation temperature of 50°C.

*1: Water cooled condenser spatial volume is calculated by subtracting the volume of the heat exchanger tube from the inside volume of the condenser.
*2: Oil quantity is minimum charge only for condensing unit.Actual oil quantity for whole of the plant (system) should be determined at the site referring the oil level of sight glasses during compressor running.Charge oil on site and replenish when the level gets lower than requested.Use specified refrigerant machine oil (Oil is requested users to supply)
*3: Water cooled type noise (scale A) indicates the values measured at 1 meter away from the compressor and 1 meter above from the floor level and air cooled type at 1.5 meter and 1 meter when the suction pressure saturated temperature is -40°C without any echo influence.In the actual installed conditions the noise level maybe different from indicated value because of the influence of surrounding noise and echo.
* : Hot gas defrost model is available optionally.
* : When suction pressure saturated temperature is required below -50°C modification for ultra low temperature with cost up is needed.
* : Noise control and harmonic suppression measurement should be taken as necessary according to respective guidelines.
* : Electric power for control circuit is requested users to supply.
* : Air cooled compressor designed atmospheric temperature is 32°C
* : Gauges for suction and discharge gas temperature are optional.
