Hello Community, I'm in the module of this device with information of values resistance and electronic links.
RE: Leica Biosystems - CM1800UPDATE 5 NOV 2019:
Does anyone out here know of a US distributor for an Elco model NU 9-20-2/094, P # NET3T09PUN302, condensor fan. Or does anyone have information regarding a compatible substitute for this condensor fan?
Please reply eMail to fredrick.tobisch@med.ge.com. Thanks.
This fan is in a Leica CM 1800 cryostat. Leica no longer supports this model, no parts, no service, no tech support. The condensor fan, installed in a Danfoss refrigeration system, is made by Elco ( Regal Benoit company ), is model # NU 9-20-2/094, P # NET3T09PUN302.
I'm pretty sure it's age is why I'm having difficulty locationg a supplier for this fan. I've checked Grainger, McMaster, Electric Motor Warehouse, PartsSource. No one seems to supply motors from this manufacturer.

Does someone here have the part number for the condensor fan in the bottom of the CM 1800 cryostat?
RE: Leica Biosystems - CM1800The above Model is old but is a necessity. At present we have a problem with the refrigeration side of it. It being old and still R12 Freon doesn't gets to its required -20 psi. What would be the best thing to do. Open for any suggestion please.
RE: Leica Biosystems - CM1800Since there is not currently a forum for the CM1800, I'll ask this question here.
Does anyone know if there is a way to add hysteresis to the temperature control of the CM1800? It turns the compressor off or on with only a one degree change, which may result in insufficient pressure equalization before the compressor restarts. Does anyone know if there is a way to add hysteresis - set it so that it takes a two-degree drop before the compressor will turn back on? I was going to install a "delay after break" time delay in the SSR control, but I've had difficulty finding an appropriate device that works in the DC control circuit. Does anyone have other suggestions?
