Home Forums General Discussion Technical Questions Glide P Door Operator

anyone have a glide p door operator they are willing to sell, looking for 2 to replace HPLIM operators. Reached out to UNITEC and was told that the Glide P was the go to operator to replace the HPLIMs. They said best bet is to reach out to the local OTIS office as they will not sell a Glide A because there is no guarantee it would work with our wiring/controller.

Please PM me if you have or know of someone who can sell.

If there's enough clearance to accommodate a hang-down drive rod from the belt, you could also leave the HPLIM in place and just decom the electronics. Then install either a GAL MONXT-OMNI (mod version) or a wittur AMD drive only. This can only be done if the controller accepts discrete signals. The GAL product might be your best bet because the belt is built into the operator and the only thing needed is resizing it. Retaining the skate and interlocks should be find as they are interchangeable with the NG locks, which are definitely not obsolete. The hang-down rod can be mounted onto either the door panel or the header.

In my opinion, HPLIM door operators were a sham to begin with. Who the heck in their right mind would buy an overbuilt piece of technology just to operate a set of elev. doors. New tech is great, but should never be taken too far. The mechanical and electronic logic of the modern European style door operator always did logically made more sense. A maglev style door operator needing a bulky hi-fi processor should have been the dead giveaway that the concept wouldn't last long in the field. Usually when a new concept looks too good to be true. It normally is too good to be true. This is why the product didn't last long in the field. Remember the saying when buying big ticket items: Buy what you need. Reasonably consider both the pros and cons of what you both need and want.

Unitec never turned down my money. Fill out the survey form mail it to them they give you a quote around $3500 put it on the account and it shows up on the loading dock.

The HPLIM from the mid-to-late 1990s had (IIRC) an Intel 386EX processor in it. That was a lot of computing horsepower in a door operator - actually a lot more than the OCSS and MCSS of the E411 car controller that it was often used with.

The HPLIM had a large copper plate as part of its linear induction motor design, with stickers that warned you that the surface could get hot. There was a LOT of current flowing to move those doors so rapidly when they opened! It was given the nickname of “the digital toaster” by at least a few mechanics that I knew.

When compared to modern linear door operators, the HPLIM is massive.

it's interesting to watch the progression over the years. the HPLIM door locks eventually became the NG door locks that most Gen2s use today. this was also the first step in the linear operations that would eventually become the AT400s and now the Glides.

The HPLIM wasn't necessarily the first linear op. This is why I classify it as a dumb design. In the NA region, Armor, Westinghouse, and Otis (7660 and 7777A) Mont. WG (similar to 7660) all produced linear operator starting from the late 60s. Even those were more closer in design to the modern linears we see today, such as MONXT, AMD/LD-16, Fermator, etc. HPLIM was just an overbuilt waste of resources.

Honestly, in terms of older door operators, I like the Otis 7080 with close coupling doors.

In terms of new door operators, I like Fermator and Schindler v35.
