Refrigerant monitors

If you had a choice what brand would you replace one with.I have ten that are not operational for several differant reasons Trane wants Pricing Removed for a gas pump and I really dont like paying them if I dont have to.At least half of them will need to be replaced the other half I can get going but I am concerned due to the age I would be better off replacing them.

Could you be more specific please? Are you trying to monitor the liquid level in a standpipe of a chiller? Hansen makes a good system that will do this, and it has all kinds of user setpoints that can be manipulated for alarms, control of solenoid valves, etc...

I worked for a Trane office. Very high percentage of monitors broke within first year and broke again after being sent out to be fixed. High repair bills. We started using Vulcain and have had very good results. I think they are owned by Honeywell now.

Yokogawa/Bacharach is a good unit. I have one that has been in service for seven years.
I do have a problem with it that just started a few days ago. I suspect the pump is the
problem. Haven't had a chance to check it yet. I only work on monitors when I don't have anything else to do.

we've installed a few of the bacharach monitors in our area recently. work well and seem less problematic than some of the others, highly recommend them

Thanks for the information I will look into the yokogawa and I have already looked into the Backarach monitors.I may take you up on the offer Frank but let me see if they are seriouse.I have a new IMC book on the way my old one is from 94 can anyone tell me if this is in a fire code in any way it may help with the customer.

Its a guideline set forth by ASHRAE Standard 15. I put in a Sentech IR about a year ago. No trouble yet.

I am a fan of the honeywell/vulcain units. you can utilize various sesnors tied to one unit, so multiple refrigerants no problem. in rinks, we also use co sensors tied to them. easy to set up, lots of bells and whistles.

Ditto.

We use Yokagowa/Bacharach monitors in the chiller plant here, years of trouble free service.

We have one sitting on the bench at work..boss wants to send it in to get rebuilt. Is this possible? unit is about 18yrs old. pump no longer runs..internal hoses deteriorated, etc, etc
