The HCS4200 for 230/277-V systems has twice the number of outputs as previously, up to 384 total, enabling it to control very large heat emitter arrays in small spaces. Additionally, the output power has been more than doubled, from 1.47 kW to 3.68 kW per 230-V heating element. The HCS4300 for 400/480-V systems has a maximum output of 7.6 kW and up to 216 outputs, allowing it to control four times as many heating elements as previously.
Coolant Transforms and Chills — Just Add Water
Frosty Tech coolant provides perpetual chilling without a power source. Adding water of any quality, including seawater, transforms the powdered cooling agent into a sub-freezing product. It becomes colder than ice in 10–30 seconds, and can maintain this temperature for several hours, even in ambient temperatures up to 95°F (35°C). The coolant powder can be regenerated and reused hundreds of times by allowing the water to evaporate; the regenerated powder retains 100% of its original cooling ability. The product can be adapted to any custom shape or volume, and to flexible or rigid packaging, and can be formulated to achieve almost any freezing point or temperature desired. It is recyclable and does not contain any toxic chemicals.

Rupture-Disc Monitoring Unit Is Reusable
The NIMU (non-invasive monitoring unit) is a rupture-disc monitor that provides reliable information about the way a bursting disc responds to positive and negative pressure. The unit is installed so that it is isolated from the process medium, making it suitable for critical processes and applications that require the entire system to be completely impermeable. The design is based on intrinsically safe, closed-circuit technology, which allows it to be easily integrated into an existing process control system using terminal boxes and isolating amplifiers. The device can be reused after a rupture disc has opened; the only requirement is that the rupture disc itself be replaced, and this can be done without opening the pipeline.
Fluids and Solids Handling
Mill Grinds Sticky, Moist, and Fragile Materials
The CM540 sanitary cone mill performs gentle, low-energy size reduction of solids while achieving even particle distribution and producing minimal fines. Material is fed pneumatically or by gravity into a central milling chamber, where a rotating impeller accelerates it centrifugally against and through apertures in a conical screen and then into a receptacle below the milling chamber. The mill is suitable for delumping dried or hygroscopic materials that have agglomerated due to dampness or compaction, for intermediate sizing of wet product to enhance drying and granulation prior to tableting, and for regrinding out-of-spec product to be reintroduced to the process. It is intended for pharmaceutical, food, and chemical applications where contamination must be avoided. Models range in diameter from 3 in. for laboratory applications to 27 in. for production capacities up to 25 tons/hr.
Drum Dumper Transfers Materials without Creating Dust
The TIP-TITE mobile drum dumper enables dust-free transfer of bulk materials from drums into process equipment and storage vessels. It is mounted on a mobile frame with quick-action floor jacks for stable operation. A hydraulic cylinder raises the drum carriage, sealing the drum rim against a discharge cone, after which a second hydraulic cylinder tips the carriage-hood assembly and drum, stopping at a preset dump angle of 45 deg., 60 deg., or 90 deg. As the assembly approaches its fully tipped position, the outlet of the discharge cone mates with a gasketed receiving-ring inlet fitted to existing process equipment or to the lid of an optional hopper with integral pneumatic, tubular cable, or flexible screw conveyor, creating a dust-tight seal. Once the discharge cone is seated against the gasket, a pneumatically actuated slide-gate valve opens to allow material to enter the receiving vessel.
Electronic Pressure-Compensation System Improves Reliability
An electronic pressure-compensation (EPC) system is now available with the manufacturer’s high-accuracy loss-in-weight feeders, or it can be retrofitted to existing feeders, even in systems with perceivable pressure fluctuations. In a closed feeding system, pressure buildup inside a feeder can significantly impair weighing accuracy. Typical mechanical pressure-compensation systems are sensitive to structural factors and machine alignment, making reliability an issue. This electronic device ensures accurate and steady pressure compensation in feeder hoppers, has a lower initial cost, and is easier to install than mechanical systems. Sensors can be positioned on the feeder hopper and, if required, on the material discharge tube.
