In this section you will find photos of heating, ventilation and airconditioning equipment that can be rebuilt and/or custom fabricated. Also, supporting components, such as duct work, are shown and can be built to your specifications.

If you don't see what you need, please email Canal Car and describe what it is that you are looking for, along with your contact information.
Heating/AC Blower

Heating and airconditioning blower rebuilt to employ a standard 240V, 1725 RPM motor, instead of the double-shaft, DC motor formerly used. Fabrication plans for the motor adapter can be found in the documentation section.

Reusable Filter Frame

The typical metal frame filters used in railway equipment are difficult to find on the road in the places that PVs frequent. Replacement filters that use readily available (e.g. from Grainger) 2" thick polyester filter material make it easier to change out the filter media, when necessary (the material can even be washed, in a pinch).

Filter Material Holder

The filter frame separates into two pieces. The side away from the air stream accepts the polyester filter material. It uses expanded metal to support and hold the filter firmly in the air stream. The frame is formed of #16 ga. m.s. sheet bent on a brake and welded on all corners.

Filter Frame Cover

The side facing the air fits exactly over the other half of the frame. It has pads for the filter clamps and uses 1/2" hardware cloth to hold the filter material in place but keep the occluded area to an absolute minimum, to maximize air flow.

Galvo Filter Material Holder

An alternative, less expensive filter frame can be fabricated from #18 ga. galvanized steel, employing spot welded construction and 1/2" hardware cloth on both faces. Check the parts department for filter frame prices and ordering information.

Galvo Filter Frame Assembly

The frames can be built to any size and shape. Thicknesses in multiples of the two inch filter media thickness are best (i.e. 2" or 4"). Here, a two inch frame has been provided with 1" clamp blocks so that it will fit into a location previously occupied by a 3" thick filter. The new, high-efficiency media will make up for any loss in filter performance due to reduced thickness.

Pleated Filter And Frame

Cardboard filters are readily available, including those that use pleated, high-efficiency filter material. The galvanized frames can be made to hold such cardboard filters and drop right in to the original filter location in the air duct. Photo by Al Dykes

Pleated Filter In Frame

Here, a pleated, cardboard filter is installed in the frame and ready to go. Since these filters are commonly available, should one need to be replaced on the road, there will be no problem finding them at the local supply depot. Photo by Al Dykes

Frame, With Bulk Filter Media, Installed

Alternately, a frame with bulk, polyester filter material is installed in the air duct. Easily removed, the frame can be opened and the filter material removed for washing, should the filter become clogged on the road. Photo by Al Dykes

Heating Thermostat

Vapor thermostat, refurbished and rewired to operate an SSR (see the documentation section), ready to be installed in a custom fabricated stainless steel pedestal enclosure.

SSR Heater Control

A 240V Solid State Relay (SSR), bolted to a suitable heat sink (in this case a metal wall) can be used to control electric baseboard heaters via the existing thermostats. Sometimes, the thermostat will have to be rewired (see the documentation section) but the SSR itself can operate directly on the 32V DC thermostat power with no need for a current limiting resistor.

Exhaust Blower

A two-speed blower can be mounted in the ceiling and vented to the outside world through a roof vent. A blower with a one third horsepower motor will provide ample air movement for most range hoods. Two speeds allow the chef a modicum of control over the amount of air flow.

Transition Elbow

In this example of a piece of custom-fabricated ducting, the connection to the range hood is through a transition (a transition elbow, in this case). It is important to be able to fabricate transitions (see the documentation section), since there are lots of instances where the ductwork must change from rectangular or square to round.
