Steam Chamber--Cast High Test Iron. Fin Surface--Aluminum alloy cast metal to metal contact with steam chamber. Manifolds or Headers--Cast high test iron. Lower outlet temperatures and greater volume delivers warm air to working zone of room, thus eliminating heat losses at ceiling and avoiding stratification. Grid Unit Heaters--Reduce fuel cost and maintenance expense--no damage possible to Grid due to electrolytic action as it cannot take place in Grid Units. Cooling and Refrigerating--Grid Unit Cooler ideal for cooling, using cold water, sodium or calcium brine or direct expansion ammonia. Write for further information and catalog. 691
