Product Description:

Product update: 220V AC flat coil and 20.0 mm coil options are also offered. 


RDK-300A is the deluxe version of our 2nd generation PID controller for the hot runner coil heater. It can be used to precisely control the temperature of a hot runner coil. It is safe, accurate, reliable and easy to use. The deluxe version has extra safety features and is more stylish.

Compared to 1st generation controller, which was assembled with existing controller components for the industrial use, the 2nd generation was built from the ground up specifically for the consumer market. The design is very clean and functional. The confusing keypad and Indicators were replaced with a rotary encoder and a power switch. The operation is intuitive and difficult to screw up.   This simple and clean appearance, however, does not mean the controller is more basic. This controller has more features than any other competitor’s product on the market. Below are some of the high lights that most other products may not offer.

Ease of Operation. Adjusting the set temperature is very simple. User only needs to tab the knob once to activate the temperature setting mode, and then turn the knob to increase or decrease the set temperature. It is just as simple as adjusting the temperature of a cooktop at home..

Real-time Parameter Adjustment. For the first generation RDK, the controller will maintain the current power output level while its parameters or set temperature are being adjusted. If the user spent slightly longer time in adjusting parameters, the coil can overheat and burn out due to the high power and low thermal mass nature of the coil. That scenario will not happen to this controller; because our 2nd generation controller has a more powerful microchip which capable to control the temperature and read the new parameters at the same time.

Hot Coil  Warning After Turned Off. A hot runner coil may take more than 25 minutes to cool down after usage. The first generation controller doesn’t provide a reliable way to warn the user if the coil is still hot after turned off. Being unaware of a hot coil may result in users get burned and contacted objects become damaged. we solves this problem by adding a delay timer for shutting off the display. When a user switches off the heater; the display will stays on and flashes "hot" and the coil temperature alternately. After the coil is cooled down to a safe-to-touch temperature (150 °F), the display will be turned off automatically.

Compensated Temperature Display. The first generation controller only display the temperature of coil. The temperature sensor is located at the tip of the coil. It does not represent the actual temperature on the top surface of the nail, which is lower normally. The difference is determined by the thermal conductivities, the surface/mass ratio, and the ambient temperature. This controller allows the user to adjust the display temperature by entering a correction coefficient, so that the displayed temperature is closely representing the surface temperature of the nail.
 
Timed Automatic Power Off. The built-in timer can automatically shut off the controller after a specified duration; This feature can preserve the coil life and make the system safer in case of the user forgot to turn the power off. The on duration can be adjusted from 1-999 minutes. This feature can also be disabled to turn off manually.

Over Temperature Protection. A electro-mechanical relay is added to cut the power to the heater off when the temperature is out of control. This is an added safety to prevent operation error or SSR failure.

Ergonomic Layout. The cables are connected to the back panel. It makes the appearance clean and safer to operate. It eliminates the potential danger of accidentally pulling the cable of the hot coil on the glass when adjusting the controller. 

Lab  Instrumenl Style Appearance. The enclosure is made of black anodized aluminum. Anodized finish is harder and more durable than the painted or powder coated enclosure. It also gives a smooth and clean look as the background for the white LED display. The dual color power switch will be in red color when controller is powered off (or standby mode) and in white color when it is powered on.

The optional 15.8mm coil is rated for 100 Watt 110V. It has 15.8 mm ID, 16 mm width. This coil is compatible with E-nail.

The optional titanium e-nail offers a perfect fit with the heating coil. Unlike some of the early design, these nails do not need converter or adapter to fit into the commonly used ash catcher. Two versions are offered. One fits with either 14 or 18 mm male glass. The other fits with 14 or 18 mm female glass. 

We also offer flat coil and universal nail. The coil is rated as 100W. The cable is 55 inch long with black Kevlar sleeve. Please refer to the supplimentary manual to adjust related parameters. 

The universal nail is made of grade 2 titanium. It has 5 disassemble pieces, which can be configured into male nail or female nail.  In either configuration, it can fit with 14 or 18mm glass.  

Note: For all the coils that we offer, the 20.0 mm coil's surface temperature is the closest to its sensor reading; its temperature correction coefficient is only 1.03 by test, please refer supplementary manual for more details.
