Why Orbetron

Orbetron was founded in 2011 to fill a niche in the low-rate bulk material feeding market, but it’s our consistent drive to design, engineer, and produce state-of-the-art equipment that has allowed us to expand internationally.

We are a customer-focused company that offers more than an off-the-shelf solution. We work with our clients to design, engineer, and manufacture customized dry and liquid bulk material feeding systems specific for your application. Our in-house design capabilities allow for variations in concept to fit most process requirements.

As technology evolves, Orbetron’s goal is to stay up to date with its cycle. At Orbetron, we’ll help you create a feeding or blending solution to fit your unique needs.
