Rising power tariffs turn energy into a major line item for any bottle plant, and the MP55D energy saving PETG blow molding equipment answers that pressure directly. Every extrusion and hydraulic motor is specified at IE3 or IE4 efficiency class, and a servo energy-saving drive can be added so the machine draws power in proportion to what each cycle actually needs rather than running flat out all shift.
On a machine that averages 23.9 kW in continuous use, trimming wasted effort from the pumps and extruder compounds across a year of three-shift operation. The saved kilowatt hours go straight to the bottom line, and the cooler running temperatures also ease wear on hydraulic oil and seals.
Key Features
- IE3 / IE4 Motors: standard high-efficiency motors on both the extruder and hydraulic pumps.
- Optional Servo Drive: servo energy-saving mode matches power draw to real cycle demand.
- Proportional Hydraulics: delivers only the pressure and flow each action needs.
- Low Average Draw: around 23.9 kW in continuous production keeps running cost predictable.
- Cooler Operation: lower heat load extends hydraulic oil and seal life.
- Higher Efficiency Class: a simple route to cut energy per thousand bottles.

- Producers matching PETG, HDPE and PP jobs on one energy-efficient frame
Energy efficiency is not only about the motor nameplate. A proportional hydraulic system and a well-tuned parison control avoid over-packing the mould, which cuts both scrap and wasted pressure. Together these measures make the PETG blow molding equipment cheaper to run per thousand bottles than older machines of the same nominal size.
Packaging and Quality Assurance
Each unit is power-logged on the test bench so the buyer receives a measured consumption figure alongside the nameplate data. Machines ship on wooden pallets with an optional crate, a wiring diagram and a startup checklist. MEPER advises on cable sizing and any local efficiency incentives so the energy saving PETG blow molding equipment qualifies for available support where offered.
Frequently Asked Questions
Q: How much energy can the MP55D PETG blow molding equipment save?
A: Savings depend on your tariff, shift pattern and the drive option selected. With IE3/IE4 motors and an optional servo drive, the machine targets the wasted effort older moulders lose to constant pump and motor loading. MEPER will supply a measured consumption figure from the test bench so you can model payback against your own electricity rate.
Q: Is the servo drive worth adding?
A: For plants running long, steady shifts with variable cycle demand, a servo drive usually pays back fastest because it trims power between the loaded stages of each cycle. For intermittent, low-volume use the standard motor set is often sufficient.
Q: Will efficiency upgrades raise the machine price a lot?
A: The base machine already ships with IE3/IE4 motors at no premium. The servo drive is the main optional step, and its cost is offset over time by lower power bills, making it a straightforward decision on any high-utilisation line.
