Solid-state circuitry assures excellent reliability and service life.


Safety Interlock.

Sturdy construction for extended service life.

Rugged water and environmentally sealed to operate in most weather.

Heavy-duty, long life, ALKALINE batteries provide efficient and dependable power.

Fast battery change, using temperature compensated circuits facilitate cold weather operation.


Use of this equipment requires training in blasting techniques. Contact your powder company representative for training information.

This equipment must be operated in accordance with US Federal health and safety standards, state laws, rules and other applicable statutory provisions.

SUITABILITY: Properly trained and skilled personnel must determine suitability and safety factors of each blast.

IMPORTANT: Devices such as the REO Blasting Machine Energy Testers must be used to determine the energy output of each circuit prior to each blast.

Lead lines shall not be connected to the blasting machine until the circuit wiring has been verified by approved testers, the blast is ready to be fired and area safety is assured.

After the lead lines have been connected to the blasting machine, depress the CHARGE switch and hold it down. When the READY TO FIRE indicator lights, depress the FIRE switch while continuing to depress the CHARGE switch. Unless the CHARGE and FIRE switches are operated together, the machine will not fire.



A lighted READY TO FIRE indicator confirms that the battery power was sufficient to charge the capacitors to the design voltage and the safety circuit is released.
The amount of time it takes for the READY TO FIRE indicator light to illuminate reflects remaining battery life. After months of firing cycles, a longer charge time will be required. However, regardless of battery condition, the full design voltage is present and the unit's safety circuits are released if the READY TO FIRE indicator is illuminated.

CD225-2J      Up to 450 charges
CD450-4J      Up to 350 charges
CD450A-22J   Up to 450 charges
CD450B-50J   Up to 475 charges
CD600B-100J  Up to 400 charges
CD1000-9J      Up to 600 charges
CD1500-10J    Up to 400 charges


  • Blasting machine cannot be fired until the design voltage is verified and the safety circuit is released.
  • Case is sealed against moisture and dust, and is shock resistant.
  • Capacitors are shunted until the "Charge" switch is depressed.
  • The two terminals are shunted until the "Fire" switch is depressed.


Each unit is tested extensively before shipment and carries a 90 day LIMITED WARRANTY. If the unit fails to test or perform due to a defect in material or workmanship and is returned with shipment prepaid to Research Energy of Ohio, Inc., 200 East Bluegrass Dr, Norwalk, Ohio 44857, it will be repaired or replaced at our option.
