If your loading or unloading arm is handling a hazardous product that requires vapory recovery to comply with health/safety & environmental regulations, loading arms can be supplied with hatch plates or hatch plugs to allow the vapor to be caputured. If you are handling a product that will require some kind of heat management, we can supply your loading with a variety of heat trace options including electric heat trace with insulation blanket, steam jacketing or ContoTrace. Typically these types of loading arms are balanced with a pneumatic counterbalance system as a conventional spring balance is not strong enough to balance the loading arm.
