Spectroline
Spectroline's Universal Dye Injection Kit (EZ-100/ECS) is the way to add fluorescent dye within air conditioning and refrigeration systems, without using additional refrigerants. Just one connection and then the handle is turned to inject the dye.
The EZ-Ject has great cost benefit, each ink cartridge treats up to 2 gallons (7.6 L) of lubricant or 25 pounds (11.3 kg) of coolant.
No need to pour, no coolants, no spills. Since the cartridges are preloaded and marked with 14 calibrations, to always introduce the correct amount of dye.
The cartridges connect easily. A built-in check valve also prevents the reflux of dye or coolant, and also prevents leaks and contamination.
Without complex assemblies, it is ideal for preventive maintenance programs and for small and medium AC&R units.
