If enough pressure is reduced across a valve, the condensation can freeze.
Our recommendation to prevent this is to use a catalytic heater on the valve body.
A standard CATCO catalytic heater package ordered from Kimray will include
all the components needed for most installations.
Depending on your valve model and site specific needs such as area classification or voltage for international use some optional components may be required.
For most installations, you'll need the following components and tools.
If you have alternative power source on location please consult your company's electrician for connecting.
To install the enclosure, simply place it around the valve then close the housing and relatch.
Connect the u-bolts to the mounting brackets on the housing to secure the unit in place.
This demo unit does not have mounting brackets but you will attach it just like you see it here in this picture.
If you are using a shutoff belt and thermocouple they will come pre-installed.
For more information about optional parts available and how they function contact Kimray's product support.
Now you're ready to make the field connections.
If you are using a shutoff valve, thread the low pressure fuel gas regulator into the inlet side of the shutoff valve with a tube fitting.
If you are not using the shutter valve, thread the tubing fitting directly into the back of the enclosure.
Install the gas supply line into the fuel gas regulator with a fitting.
This tubing is just for our demonstration.
You will need to consult your company guidelines for tubing requirements.
Installation is limited to connecting to a suitable gas supply.
Heaters may be started using either DC or AC power making them ideal heating sources for
remote locations where electrical power is limited or not available.
For natural gas fire heaters fuel gas is usually readily available on site.
If you have wet gas it is helpful to install a Kimray tripod to remove any excess liquids.
Simply mount the drip pot vertically and connect it
between your fuel gas source and your low pressure fuel regulator.
Next, connect the wires from the battery cables to the terminals inside the junction box with a
small crescent wrench or end wrench.
Either cable black or white can be connected to either terminal.
Use a screwdriver to close the connection in the junction box or channel locks if you are using an
optional explosion proof box and replace the cover.
There are two ways to start the CATCO heater.
Local power source or battery cables.
If you have an alternative power source on location you will need to consult your company's electricians for connecting these components.
For starting using battery cables, turn on your vehicle then connect the cables to the battery on your vehicle.
Leave your fuel gas shut off.
This allows the catalytic reaction that produces heat to begin.
The catalyst bed must be preheated to approximately 250 degrees and will take approximately 15 minutes to come up to temperature.
Once the catalyst bed has been preheated, open your fuel gas line.
If you are not using a shut off valve, simply opening the fuel gas line will start the catalytic reaction.
If you do have a shutoff valve installed press and release the button to start the flow of fuel gas to the heater to start the catalytic reaction.
Leave the connection for 5-10 minutes until the catalytic reaction is fully established.
This will be indicated by a rapid rise in phase temperature.
Once the reaction is established, disconnect the cables from your vehicle.
If an electrician has hardwired the power the electrical power can now be turned off.
Once the heater is in normal operations you can roll up the cables and set them aside.
This chemical reaction will continue for as long as the heater is provided with a clean fuel supply.
To shut down the heater, turn off the fuel supply to cause the catalytic reaction to stop.
Be sure not to handle the unit until it's sufficiently cooled.
