South America Montevideo, Uruguay South America SCOTCH WET BACK HEATING BOILERS Series 3000, for packaged heating units. These boilers can be used with any manu facturer's burner equipment. Two-pass design gives good distribution of heat transfer with low stack temperatures and permits easy access to tubes. Large water and steam space assures smooth opera tion, steady pressure, and constant heat. Among the features are: Wet front furnace--Front end of furnace, with water all around, is flush with front of boiler. Burner can be connected to fire directly at water heating surface without heat loss. Complete wet back--Entire combustion chamber is surrounded by water, for efficient and quick conversion of water to steam. There is no heat waste in rear; boiler room is.cooler. Sizes from 4200 to 70,000 sq ft of steam radiation. SCOTCH WET BACK HEATING BOILERS Series 2600 Where economy of installation and op eration are paramount and the space is small, F & T Series 2600 Boilers are ideal. No expensive foundations, pits, or ex ternal brick work are needed. Piping to boiler is easily installed, especially where headroom is at a minimum. Steam space extends the entire length of the boiler, since the surface above the rear combustion chamber is covered with water. This provides large steam space and disengaging area. Series 2600 boilers are self-contained and can be moved easily and installed on two saddles. All parts are readily acces sible for inspection and cleaning. Boilers can be furnished with special front.furnace extension to suit burner require ments. Sizes from 3160 to 42,500 sq ft of steam radiation. BISON COMPACT HEATING BOILERS Bison Compact Heating Boilers are designed to have a large furnace volume, ample water and steam storage, proper steam liberating surface and a balanced circulation. The result is a remarkably steady waterline. Original cost of Bison Compact Heating Boilers is low and they are easily installed. They come complete, ready for pip ing. Minimum brick work is required. These boilers are de signed for mechanical firing with oil, gas or stoker, but can be made for hand firing with anthracite or bituminous coal. Sizes from 2680 to 42,500 sq ft of steam radiation. 1554 Heating Systems Balm, Gas HXOBSTherm i Northvale, New Jersey HYDROTHERM The "Packaged" Automatic Gas Heating Plant.
