Pouring Cups
TXPF Filter Holders
Tested thoroughly for performance
Select from a range of highly exothermic and insulating grades
Low Fume grades for improved atmospheric conditions.
Direct Pour Units
Exothermic TXPF Pouring Units
For Iron & Steel Castings
This is a direct pour unit with filter holder. Made from highly exothermic material it can be placed directly on to a casting and act as both the feeder and pouring bush. Comes in a range of sizes to accomodate a 70mm dia filter all the way up to a 200mm dia filter.
Exothermic Hot Topping Compounds
A Range of Exothermic Powders to Boost Feeder Temperatures
ALUMINIUM AND COPPER ALLOYS
Highly Exothermic Topping Compound
Exofeed AL412
Slow Ignition
Exofeed AL412 is highly exothermic topping powder with a fast and hot ignition. It's formulated for smaller risers.
Highly Exothermic Topping Compound
Exofeed AL413
Medium Ignition Speed & Insulating
Exofeed AL413 has a slightly slower ignition time compared to AL412 but is lower in smoke generation. A key difference is, the crust retains heat long after the initial burn so it has improved heat retention charateristics.
Exothermic Topping Compound
Exofeed AL416
Fast Firing & Insulating
Exofeed AL416 is designed for large diameter risers and where fume must be kept to a minimum in the working environment.
Its burn speed is quick but the exothermic heat output is lower to control fume levels. For this reason it is only suitable for large risers that need a mild exothermic boost and insulating crust.
IRON AND STEEL
Highly Exothermic Topping Compound
Ecofeed Fe431
Fast Firing
Fe431 is a fast firing, very exothermic topping powder for smaller feeders (1 inch to 4 inch). It produces slightly more fume that the other 2 grades but benefits from very hot temperatures.
LOW Fume Topping Compound
Ecofeed Fe433
Mildly Exothermic and Insulating.
Fe433 is a low fume, medium exothermic topping powder with excellent insulation properties. It ignites at a slower speed for large feeder heads of 8 inches and higher.
Exothermic & Insulating
Ecofeed Fe435
Balanced performance
Fe435 is an exothermic powder for medium-sized feeders (4 inch to 10 inch). Produces a balanced exothermic reaction with good insulating properties and lower fume.
