    Experience with a specific screw compressor



    I am located in the central USA and we manufacturer commercial and industrial chiller and condensing units with screws and recip compressor. Nearly all of them are semihermetic.

    For screws we have been using Copeland/Bitzer with very few problems. Our alternate supplier has been Refcomp and now we are unsure of their dedication and stability to the US market. Recently Hanbell (Taiwan) has moved into the US market and it seems to be a well designed compressor. We are planning to prototype and test a couple of systems with the Hanbell compressor.

    Would appreciate any feed back and experiences on the Hanbell compressor.

    Thanks,
    Ken

    We are a distributor of Hanbell Screw Compressor in the Philippines, mostly in the retrofit market, so far this compressor is quite reliable, the design of the unit is basically simmilar to Hitachi, out of 60 units sold only 4 have had problem and most are more than 5 years old.

    Hope this help.

    We are very familiar with MSC and have worked with them on controls and looking at using a Hanbell in a prototype/test bed unit to see what we can throw at it.

    Hi, Ken

    Very good decision

    Re: Experience with a specific screw compressor

    We distribute Hanbell in the UK and can recommend them.

    We have supplied over 90 in the past year, mostly to replace recips, and only one failed, due to a commissioning issue concerning contactors.

    Some of the earlier models (larger sizes V5 / V6) were susceptible to slide valve problems if the loading sequence was too fast, but the valve assembly has been re-designed and this seems to have eliminated the problem.

    These are also used by many chiller makers as original fit machines.

    Hi Ken,
    and Hello to everyone,
    I am a new member to this forum and would like to share some of my views on Hanbel screw compressors. Generally they are very good and reliable, we have 12 of them in total (by the way I am from Abu Dhabi in the U.A.E.) all of them on
    mobile flat beds. One problem we have been hit with is the Oil level float safety switch, they have got pin holes around the periphery and at the top near the centre tube. The float no longer floats....Has anyone else using these compressors faced such similar and if so what is the fix. WHERE CAN WE GET RELIABLE REPLACEMENT FLOAT SWITCHES..??

    Re: Experience with a specific screw compressor

    I am very familiar with this problem. The float would break because of sudden inrush of oil banging it on the upper wall.Once the float breaks it no longer floats!
    There is a new design available . also a partition has been introduced to stop sudden oil inrush .
    Please et me know if you need 12 replacements.

    Re: Experience with a specific screw compressor

    Hi

    As UK Distributor for Hanbell we have supplied a large qty of both RC10 & RC11 models to replace recip Copelands around 85 to 100 ton (American). These were fitted to American Mammoth DX chillers.

    We have some 110 or so of these models now in service and find the upgrade quite straightforward.

    Our market in the UK is primarily retrofit, and we have found very few problems at all with Hanbell. We have replaced McQuay; Daikin; Copeland; York; Trane; Maneurop; Carrier; Bitzer; Refcomp; Dunham Bush (Hartford).

    The Screw also provides the option of Variable stepless load control instead of step. This would require an external electronic controller, but some excellent models are available.

    I would suggest you contact Brian Walterick at MCS in Fort Myers Florida, who promote their own excellent retrofit chiller controller, and are currently the US Distributor for Hanbell.

    If you do please mention us.
