The PR-1500 Series Tablet Presses

View of PR-1500 Tablet Press with Doors Closed

The PTK PR-1500 series is an modern, single-sided rotary tablet press with pre-compression and a built-in turret change system designed in accordance with cGMP guidelines.

The PR-1500 Series presses feature an ergonomic, symmetrical design with locking clamshell style doors providing easy access to the compression zone for a comfortable working environment.

The PS-Con control and data acquisition software incorporates the PWR (PharmTech Weight Regulation) system utilizing displacement and force sensors to effectively monitor and regulate tablet weights within a user specified range. The PS-Con 21 CFR Part 11 compliant software features a user-friendly HMI interface that allows for recording and control of all main process  parameters, events and allows for establishment of recipe files. Data acquisition affords the ability to learn more about a product's compression characteristics so that the manufacturer can optimize tablet compression and downstream processes for greater efficiency.

The built-in swivel-arm lifting device provides a fast, easy and safe means of changing the turret. The turret is easily raised and lowered with the remote control. Additionally, the swivel arm constantly presses down on the turret during operation that prevents wobbling and trembling during high-speed operation. A load cell on the swivel arm measures the operating pressure applied to the turret. 

The zero-clearance powder feeder continuously applies a force onto the die table, thereby, reducing dust and material loss. The feeder and feeder base can be dismantled without any special tools. Different types of impellers and optional powder feeding solutions can be used to improve the feeding of poorly flowing powders.

The press is built around a robust frame constructed to withstand the considerable forces encountered during rotary press operation. Identical, vibration free pre- and main- compression rollers are controlled by servomotors that provide precise positioning. Internal covers are fitted to prevent dust from migrating into the roller assemblies and cam tracks. The covers can be easily fitted and detached without tools.

A wide range of options are available for the press and the customer will benefit from AC Compacting's extensive tablet press experience and philosophy of customer support.
