Since anhydrous ammonia can also be used in the production of methamphetamines, fertilizer dealers, farm equipment suppliers and farmers face the growing problem of protecting nurse tanks stored on their premises from drug dealers, who steal anhydrous ammonia for their illegal operations.
"Installing a high-security lock is one of the best ways to protect nurse tanks from theft and tampering," said Joe McClain, Highfield's vice president and general manager. "Our customers tell us that since installing FieldGuard tank locks on their nurse tanks, they have eliminated anhydrous ammonia theft."
The FieldGuard offers a number of advantages over competitive products, the company said. Made of stainless steel and powder-coated metal, it does not corrode when exposed to anhydrous ammonia. Also, it is designed to lock off the outlet of the nurse tank valve to minimize dangerous and costly product leakage. The FieldGuard features Highfield's proprietary REVPRO barrel lock technology that gives dealers the option of having unique key coding on their nurse tanks, for added security.
The FieldGuard tank lock assembly includes a bright orange valve bracket and can be easily installed without using any special tools.
Highfield is marketing the FieldGuard through a partnership with Venedy, Ill.,-based Terayne Ag Specialties Inc., an ag retailer with more than 30 years in the anhydrous ammonia business. They were instrumental in the development of the FieldGuard and have used it in their own facilities with great success.
