They provide detailed lifecycle assessments for each piece of equipment, so you know exactly how your purchase impacts the planet over time. “We wanted to be sure our new filtration system aligned with our corporate sustainability goals,” explains Sarah, an operations director at a beverage company. “EcoTech didn’t just sell us a press—they walked us through how it would help us hit our carbon targets. That level of partnership is invaluable.”

3. Industrial Press Systems (IPS)

When it comes to durability, few suppliers can match Industrial Press Systems. Headquartered in Chicago, Illinois, IPS has been around since 1952, and their decades of experience shine through in the ruggedness of their equipment. If your operation involves heavy-duty materials like sludge from steel mills or mining tailings, IPS’s filter presses are built to handle the abuse.

Their product line includes both standard and custom filter press equipment , with a focus on high-pressure models that deliver superior dewatering results. Many of their presses are paired with wet process equipment , which is ideal for industries where water-based slurries are common. Take the automotive manufacturing sector, for example—IPS’s wet process filter presses are widely used to separate paint sludge from water, allowing factories to recycle up to 90% of their process water.

What really earns IPS loyalty is their equipment’s longevity. “We’ve had an IPS filter press in our facility for over 20 years,” says Tom, a maintenance supervisor at a steel plant in Ohio. “It’s gone through countless upgrades, but the core frame and hydraulics are still original. You just don’t see that kind of build quality anymore.” IPS also offers comprehensive maintenance training, so your team can keep the equipment running smoothly for decades to come. If reliability and long-term performance are your top priorities, IPS is a solid bet.

4. Innovative Separation Technologies (IST)

For businesses that crave cutting-edge technology, Innovative Separation Technologies is the way to go.
